The compound falls, 4 November 1979

Between 300 and 500 Iranian students seized the U.S. Embassy in Tehran on 4 November 1979, citing the deposed shah’s admission to the United States as their justification. The embassy security officer walked out to negotiate and was seized himself; four Marine guards were taken as the attackers entered the chancery.

Employees held the upper floor for roughly two hours while the occupiers worked against the barriers with fire and a cutting torch.

The listing’s numbers mix separate moments

“90 hostages, 53 of whom are American” blends two different counts. Roughly 90 was an early estimate; the settled accounting is 66 captured Americans, three of them detained at the Foreign Ministry rather than the compound.

Thirteen were released on 19–20 November, leaving 53. Richard Queen’s release in July 1980 brought the number to 52, who were held until 20 January 1981 — 444 days in all.

Six other American diplomats evaded capture and were sheltered by Canadian and Swedish colleagues until their extraction in January 1980; they were never among the 66.

What turned a takeover into a crisis

The shah had been admitted to the United States on 22 October for medical treatment, not granted political asylum. A Tehran radio broadcast reported that the occupiers demanded his extradition.

Ayatollah Khomeini endorsed the occupation after it happened, which prevented the provisional government from ending it. Prime minister Mehdi Bazargan had condemned the seizure and demanded unconditional release; his government resigned on 6 November.

There was no enactment day

Nothing in 1979 was signed into force. In January, People’s Daily and Xinhua publicly called for one child per couple — two at most — and repeated proposals to reward one-child pledges and penalize larger families.

In June, People’s Daily reported family-planning leader Chen Muhua’s call to move the focus of birth-control work toward one-child families. A scholarly reconstruction dates the announcement encouraging all couples to restrict themselves to one child to January 1979.

Central advocacy, provincial rules

The policy was never a single national statute or government order. Provincial authorities translated central advocacy into enforceable quotas, incentives, penalties and exceptions, and those varied by locality, hukou status, ethnicity and family circumstance.

The Central Committee’s Open Letter of 25 September 1980 is the usual marker for the nationwide launch. It asked Party and Youth League members to lead by having one child; it was not itself a one-child law.

What the policy is credited with, and what it did not do alone

Fertility had already fallen from 5.8 children per woman in 1970 to 2.8 in 1979, under the earlier “later, longer, fewer” campaign — so the policy cannot be assigned the whole decline.

The familiar figures that 35.4 percent of the population faced a strict one-child rule and 53.6 percent a conditional 1.5-child rule come from late-1990s local-policy data, not from 1984.

On the sex ratio, research links the fertility constraint to elevated ratios, but son preference and access to prenatal sex selection were essential interacting causes rather than incidental ones.

26 January 1980

Egypt and Israel put major normalization measures into operation on 26 January 1980, opening land, sea and air links and initiating direct telephone and postal connections.

Regular civilian flights between Tel Aviv and Cairo were scheduled to begin that day, under arrangements Anwar Sadat and Menachem Begin had settled at their Aswan summit earlier in the month.

Triggered by a withdrawal, not a ceremony

Israel had completed the peace treaty’s interim Sinai withdrawal the previous day, transferring about 5,500 square miles of territory and its facilities to Egypt.

The treaty made that completion the trigger: diplomatic and consular relations and an ambassadorial exchange were required upon the withdrawal.

Three dates, three different steps

Resident ambassadors were not exchanged on 26 January. Saad Mortada took up his post in Israel and Eliahu Ben-Elissar his in Cairo a month later, on 26 February.

A U.S. diplomatic report instead dates the establishment of “normal and friendly relations” to 25 January, when the withdrawal finished. The three dates describe successive legal and practical steps rather than competing claims.

None of them ended the state of war. That happened when the treaty entered into force through the exchange of ratifications on 25 April 1979.

The Ster club room, 17 September 1980

Representatives of Inter-Enterprise Founding Committees and Inter-Enterprise Workers’ Commissions from across Poland met in the Ster club room at the Gdańsk union headquarters on 17 September 1980.

They decided that the local independent unions would register jointly as one nationwide organization — the Independent Self-Governing Trade Union “Solidarity,” NSZZ “Solidarność” — and created national coordinating and founding bodies, with Lech Wałęsa chairing the provisional National Coordinating Commission.

One union, or many easier targets

The choice on the table was tactical: separate regional unions that the authorities could isolate one at a time, or a single national body. Legal adviser Jan Olszewski argued for joint nationwide registration, and the meeting accepted the name proposed by Lower Silesian representative Karol Modzelewski.

A communiqué issued that day reported that more than three million workers in roughly 3,500 workplaces had joined or declared an intention to join the new independent unions.

Not the strike, not the congress

The Gdańsk Shipyard strike had already ended with the agreement of 31 August, which accepted the principle of unions independent of the communist authorities — the date often called Solidarity’s birth. 17 September was the separate decision to make one nationwide union out of it.

It was not the union’s First National Congress either; that met in 1981. Seven days after the Gdańsk meeting, on 24 September, the delegation applied for registration in the Warsaw Provincial Court.

A document dated 30 September 1980

Digital Equipment Corporation, Intel and Xerox jointly published Version 1.0 of “The Ethernet: A Local Area Network—Data Link Layer and Physical Layer Specifications,” dated 30 September 1980.

It converted work on an earlier Xerox prototype into a shared, multi-company design reference covering both layers. Publication itself was the day’s change: not a first installation, and not a product.

What Version 1.0 fixed

The specification called for Manchester encoding at 10 million bits per second, over a network spanning up to 2.5 kilometres with as many as 1,024 stations.

Its frame used six-octet destination and source addresses, a two-octet protocol-type field, 46 to 1,500 data octets and a four-octet frame-check sequence — a valid frame of 64 to 1,518 octets, limits still recognizable in Ethernet decades later.

Not Ethernet II, not 802.3

This was DIX Version 1.0. “Ethernet II” normally refers to the superseding DIX Version 2.0, published in 1982, so calling the September 1980 output the Ethernet II frame format misnames it.

Ethernet also already existed experimentally at Xerox PARC, initially at roughly 3 Mbit/s. What 1980 added was a 10-Mbit/s multi-vendor design.

The three-company specification was then offered to the newly formed IEEE 802 group; IEEE’s first Ethernet standard, 802.3, followed in 1983.

Election night, 4 November 1980

Americans voted on 4 November 1980 for presidential electors pledged principally to Republican Ronald Reagan, Democratic incumbent Jimmy Carter or independent John Anderson. Returns made Reagan the clear winner of the popular vote and of the projected Electoral College majority.

The Federal Election Commission’s compilation from official state sources gives Reagan 43,899,248 votes (50.75 percent), Carter 35,481,435 (41.02 percent) and Anderson 5,719,437 (6.61 percent) — more than 5.7 million votes and no electoral votes at all.

The concession came early

Carter telephoned Reagan to congratulate him and conceded publicly that night, saying the call had taken place about an hour earlier. Voting had not finished in parts of the West, a circumstance that later fed congressional scrutiny of early network projections and concessions.

Reagan gave his victory speech in Los Angeles alongside running mate George Bush.

What the night did not settle

The 489–49 electoral tally was the later certified result, not a vote cast by electors on 4 November; the enormous margin rests on just over half the popular vote.

Carter also remained president and continued governing until Reagan’s inauguration on 20 January 1981.

And whether 1980 amounted to a conservative realignment is disputed: contemporary scholarship described the result as dealignment, or a repudiation of Carter without a broad ideological mandate.

The eighth anniversary parade, 6 October 1981

Anwar Sadat was in Cairo on 6 October 1981 for the military parade marking eight years since Egypt’s opening attack and Suez Canal crossing in the October 1973 war.

As Mirage jets flew over, a military vehicle stopped in front of the reviewing stand and assailants attacked with grenades and automatic weapons. The squad was led by army First Lieutenant Khalid al-Islambuli and was connected to the militant al-Jihad movement.

Two hours at Maadi

Sadat was flown to Maadi Armed Forces Hospital in a coma. Doctors attempted transfusions, cardiac massage, electric shocks and chest surgery.

Eleven doctors signed the official bulletin recording that treatment. It declared him dead at 2:40 p.m.

The state the plotters wanted to topple did not fall

The conspirators aimed not merely to kill Sadat but to bring down the government and establish an Islamic order. Instead, People’s Assembly speaker Sufi Abu Taleb became acting president under the constitution and declared a state of emergency, and Vice President Hosni Mubarak emerged as the designated successor.

Motive is not reducible to the peace treaty with Israel. Scholarship identifies Sadat’s September 1981 mass arrests of religious and political opponents as a direct catalyst, alongside grievances over Islamic law and the character of his rule.

Egypt continued to observe the treaty; Israel’s final Sinai withdrawal under it came on 25 April 1982, after Sadat’s death.

White flags before the paperwork

After British troops took Wireless Ridge and Mount Tumbledown on 14 June 1982, Argentine troops withdrew toward Stanley, discarding weapons and showing white flags. British forces were ordered to fire only in self-defence while surrender talks began.

Margaret Thatcher told the House of Commons that white flags were visible over Stanley and that talks were under way. Deputy commander John Waters conducted the initial discussions while Major General Jeremy Moore travelled into the town.

What Menéndez signed

Brigadier General Mario Benjamín Menéndez surrendered the Argentine land, sea and air forces in the Falkland Islands to Moore. The instrument required Argentine personnel to assemble, surrender their arms and equipment, obey British movement and accommodation orders, and be treated according to the 1949 Geneva Convention.

Its scope was wider than the listing suggests: it expressly covered forces around Stanley, elsewhere on East and West Falkland, and on the outlying islands — not merely the capital’s garrison.

A field surrender, not a settlement

The signed text says “surrender,” not “unconditional surrender,” and it ended organized fighting on the islands 74 days after the 2 April invasion.

Parliament distinguished this from a cessation of hostilities across the South Atlantic; as of 17 June Britain was still awaiting Argentine confirmation.

A surrender of forces in the field also settled nothing about sovereignty, which remained disputed.

A letter and three phone calls

On 12 August 1982, Mexican finance secretary Jesús Silva Herzog sent creditors a letter stating that Mexico could not pay principal falling due on Monday, 16 August.

He then telephoned IMF managing director Jacques de Larosière, Federal Reserve chairman Paul Volcker and U.S. Treasury secretary Donald Regan to report exhausted reserves and the inability to meet the obligation — and flew to Washington with other officials to seek emergency assistance in person.

The same day, at home

Mexico closed its exchange markets, required dollar-denominated bank deposits to be paid in pesos, and set an official rate of 69.5 pesos per dollar against roughly 75 in the market.

Debt negotiator José Ángel Gurría had reported that banks were refusing to roll over principal. The GAO puts the external debt at about US$80 billion, roughly US$25 billion of it owed to U.S. banks.

Not an announcement, and not yet a regional crisis

The listing’s “announces it is unable to pay” compresses a private sequence: a creditor letter, calls to three of the world’s most powerful financial officials, and exchange-control measures.

Mexico said it could not meet imminent principal payments. It did not repudiate its debt, and no legal insolvency was adjudicated.

The 90-day standstill request came later, at a meeting with commercial creditors on 20 August, and the wider Latin American debt crisis unfolded over the following months rather than spreading before 12 August was out.

Two applications, 14 November 1983

FDA’s current Drugs@FDA record assigns 14 November 1983 to the original approval of Sandimmune injectable cyclosporine, NDA 050573, classed as a priority Type 1 new molecular entity. The federal administrative record adds the oral solution, NDA 50-574, on the same date.

The indication was prevention of rejection in heart, kidney and liver transplants. Strengths were 50 mg/mL injectable and 100 mg/mL oral solution; the familiar soft-gel capsule application came later, in 1990.

One source says September

A contemporary Washington Post report dated 3 September 1983 said FDA commissioner Arthur Hull Hayes Jr. had approved cyclosporine on 2 September.

The surviving sources do not fully explain the gap. 14 November is best treated as the formal product and NDA action date rather than unquestionably the first FDA authorization announcement.

The drug was already five years into patients

Approval did not create the therapy. Roy Calne’s Cambridge team had begun clinical solid-organ trials in 1978 and U.S. investigational trials followed in 1979; Thomas Starzl developed the cyclosporine-plus-low-dose-steroid approach that improved the balance between rejection control and toxicity.

What 14 November changed was availability: cyclosporine moved from limited clinical investigation to a generally marketable U.S. transplant medicine.

It did not eliminate rejection or toxicity either. The label requires specialist supervision and monitoring and warns of nephrotoxicity, infection and lymphoma risks.

The Flint Center, 24 January 1984

Steve Jobs unveiled the Macintosh at Apple’s annual shareholders’ meeting on 24 January 1984, held at the Flint Center on the De Anza College campus in Cupertino. He demonstrated its graphical interface, mouse-driven applications and synthesized speech, and replayed the “1984” advertisement.

The event overflowed the hall, leaving many Apple shareholders outside and producing an immediate crowd-control controversy.

What you could buy that day

Apple’s same-day press release said the machine was already available through dealerships — not announced for future shipment. The price was US$2,495.

The launch configuration had 128 KB of RAM and 64 KB of ROM, an 8 MHz processor, a nine-inch 512×342-pixel monochrome screen, a mouse and a graphical desktop, with MacWrite and MacPaint included during the introductory offer. Apple’s Lisa had launched the previous year at US$9,995.

Three things the anniversary usually gets wrong

The Super Bowl commercial aired on 22 January; the unveiling and dealer launch were the 24th. Jobs then repeated the presentation for the Boston Computer Society on 30 January, and footage from that better-recorded demonstration is often mislabeled as launch day.

Apple invented neither the graphical interface nor the mouse — Xerox systems and Apple’s own Lisa came first. Its distinction was an integrated GUI machine that reached a broad market.

And the first year undershot: 275,000 Macintoshes sold in 1984 against a preliminary projection of 563,000.

Beijing, 26 September 1984

British ambassador Richard Evans and Chinese vice-foreign minister Zhou Nan, the leaders of the two negotiating teams, initialled the draft Joint Declaration on Hong Kong in Beijing on 26 September 1984.

Negotiators had settled the remaining issues four days earlier, on 22 September, closing talks that had begun in 1982.

Published the same day

The draft comprised a joint declaration and three annexes, released that day as a White Paper in London and Hong Kong and laid before the British Parliament. More than two million White Paper copies were subsequently distributed in Hong Kong.

Its published terms said China would resume sovereignty and Britain would restore Hong Kong on 1 July 1997, with Hong Kong becoming a Special Administrative Region whose stated basic policies would remain unchanged for 50 years.

Initialling is not signing

What existed after 26 September was an initialled draft entering political consultation — not a signed, ratified or legally binding treaty. Margaret Thatcher and premier Zhao Ziyang signed the completed declaration on 19 December 1984, and it entered into force only when ratification instruments were exchanged in May 1985.

The territory’s legal position was not uniform either: only the New Territories and New Kowloon were held under the 99-year lease of 1898. Hong Kong Island was ceded in 1842 and southern Kowloon in 1860, under different instruments.
