Ahmadiyya, officially the Ahmadiyya Muslim Jama'at is an Islamic messianic movement originating in British India in the late 19th century. It was founded by Mirza Ghulam Ahmad (1835–1908), who said he had been divinely appointed as both the promised Messiah and Mahdi expected by Muslims to appear towards the end times and bring about, by peaceful means, the final triumph of Islam; as well as to embody, in this capacity, the expected eschatological figure of other major religious traditions. Adherents of the Ahmadiyya—a term adopted expressly in reference to Muhammad's alternative name Ahmad—are known as Ahmadi Muslims or simply Ahmadis.

On March 23, 1913—Easter Sunday—a devastating tornado outbreak affected the northern Great Plains and sections of the Upper Midwest, lasting approximately 31⁄2 hours. It was the most violent tornado outbreak to affect the northern Great Plains on so early a date in the year—a record that still stands as of 2020. That day, four F4 tornadoes affected portions of eastern Nebraska and western Iowa, killing at least 168 people. The deadliest tornado of the day was a violent tornado, retroactively rated F4 on the present-day Fujita scale, that grew to 1⁄4 mile (440 yd) in width as it passed through northern Omaha, Nebraska, killing at least 94 people in the city proper and three in rural areas. Damage in Omaha reached at least F4, possibly even F5, intensity, though confirmation of F5 damage could not be determined from available evidence. The tornado is the 13th deadliest ever to affect the United States and the deadliest to hit the U.S. state of Nebraska as of 2024. No other violent tornado would affect Omaha for another 62 years. Outside the Great Plains, the outbreak of March 23 also produced two other F4 tornadoes, one each in Missouri and Indiana, including a devastating path more than 1⁄2 mi (880 yd) through southern Terre Haute, Indiana, killing 21 people and injuring 250. In all, tornadoes struck Nebraska, Iowa, Louisiana, Indiana, and Missouri, though only significant events were recorded and other, weaker tornadoes may have gone undetected.

In 1980, Romero was fatally shot by an assassin while celebrating Mass. Though no one was ever convicted for the crime, investigations by the UN-created Truth Commission for El Salvador concluded that Major Roberto D'Aubuisson, a death squad leader and later founder of the right-wing Nationalist Republican Alliance (ARENA) political party, had ordered the killing.

The Suez Canal was blocked for six days from 23 to 29 March 2021 by the Ever Given, a container ship that had run aground in the canal. The 400-metre-long (1,300 ft), 224,000-ton, 20,000 TEU vessel was buffeted by strong winds on the morning of 23 March, and ended up wedged across the waterway with its bow and stern stuck on opposite canal banks, blocking all traffic until it could be freed. Egyptian authorities said that "technical or human errors" may have also been involved. The obstruction occurred south of the two-channel section of the canal, so other ships could not pass. The Suez Canal Authority (SCA) hired Royal Boskalis through its subsidiary Smit International to manage marine salvage operations. The blockage of one of the world's busiest trade routes slowed trade between Europe, Asia, and the Middle East, tying up goods worth an estimated US$9.6 billion per day. By 28 March, at least 369 ships were queuing to pass through the canal.
