The Kiel Canal is a 98-kilometer-long (61 mi) freshwater canal that links the North Sea to the Baltic Sea. It runs through the German state of Schleswig-Holstein, from Brunsbüttel, at the mouth of the Elbe, to Holtenau, on the Kiel Fjord. It was constructed between 1887 and 1895 and widened between 1907 and 1914. In addition to the two sea entrances, the canal is linked at Oldenbüttel to the navigable River Eider by the short Gieselau Canal.

Eduard Gustav Freiherr von Toll, better known in Russia as Eduard Vasilyevich Toll and often referred to as Baron von Toll, was a Russian geologist and Arctic explorer. He led the Russian polar expedition of 1900–1902 in search of the legendary Sannikov Land, a phantom island purported to lie off Russia's Arctic coast. During the expedition, Toll and a small party of explorers disappeared from Bennett Island, and their fate remains unknown to this day.

The 28th International Eucharistic Congress was held in Chicago, Illinois, United States from June 20 to 24, 1926. The event, held by the Catholic Church, was a eucharistic congress, which is a large scale gathering of Catholics that focuses on the Eucharist and other items of Catholic faith. The event was organized by Cardinal George Mundelein, the Archbishop of Chicago, and was the first International Eucharistic Congress held in the United States and the second held in North America. Cardinal Giovanni Bonzano served as the papal legate for the event. The event attracted a large number of people to the city, with most sources claiming at least several hundred thousand attendees. Large events were held throughout the area, at locations including Soldier Field, Holy Name Cathedral, and the Saint Mary of the Lake Seminary. Some sources claim that approximately 1 million people attended the closing day Mass held at the seminary in nearby Mundelein, Illinois.

The 1943 Detroit race riot took place in Detroit, Michigan, from the evening of June 20 through to the early morning of June 22. It occurred in a period of dramatic population increase and social tensions associated with the military buildup of U.S. participation in World War II, as Detroit's automotive industry was converted to the war effort. Existing social tensions and housing shortages were exacerbated by racist feelings about the arrival of nearly 400,000 migrants, both African-American and White Southerners, from the Southeastern United States between 1941 and 1943. The migrants competed for space and jobs against the city's residents as well as against European immigrants and their descendants. The riot escalated after a false rumor spread that a mob of white people had thrown a black mother and her baby into the Detroit River. Black people looted and destroyed white property as retaliation. White people overran Woodward to Veron where they proceeded to violently attack black community members and tip over 20 cars that belonged to black families.

The Battle of the Philippine Sea was a major naval battle of World War II on 19–20 June 1944 that eliminated the Imperial Japanese Navy's ability to conduct large-scale carrier actions. It took place during the United States' amphibious reconquest of the Mariana Islands during the Pacific War. The battle was the last of five major "carrier-versus-carrier" engagements between American and Japanese naval forces, and pitted elements of the United States Navy's Fifth Fleet against ships and aircraft of the Imperial Japanese Navy's Mobile Fleet and nearby island garrisons. The battle was the largest carrier-to-carrier engagement in history, involving 24 aircraft carriers, deploying roughly 1,350 carrier-based aircraft.

MW 18014 was a German A-4 test rocket launched on 20 June 1944, at the Peenemünde Army Research Center in Peenemünde. It was the first man-made object to reach outer space, attaining an apogee of 176 kilometres (109 mi), well above the Kármán line that was established later as the lowest altitude of space. It was a vertical test launch and was not intended to reach orbital velocity, so it returned and impacted Earth, making it the first sub-orbital spaceflight.

The Deutsche Mark, abbreviated "DM" or "D-Mark" ( ), was the official currency of West Germany from 1948 until 1990, and then unified Germany from 1990 until the adoption of the euro in 2002. In English, it was typically called the "Deutschmark". One Deutsche Mark was divided into 100 pfennigs.

The 1959 Escuminac disaster, also known as the Escuminac hurricane, was considered the worst fishing-related disaster in the Canadian province of New Brunswick in 100 years. It occurred due to the extratropical remnants of an Atlantic hurricane. The storm was the third tropical cyclone and first hurricane of the 1959 Atlantic hurricane season, and developed from a tropical wave in the central Gulf of Mexico on June 18. It headed rapidly northeastward and struck Florida later that day. Shortly after entering the Atlantic Ocean, it strengthened into a tropical storm later on June 18. By the following day, it had strengthened into a hurricane. However, it transitioned into an extratropical cyclone about six hours later. The remnants struck Atlantic Canada, once in Nova Scotia and again in Newfoundland before dissipating on June 21.

The Cuban Missile Crisis, also known as the October Crisis in Cuba, or the Caribbean Crisis, was a 13-day confrontation between the governments of the United States and the Soviet Union, when American deployments of nuclear missiles in the United Kingdom, Italy and Turkey were matched by Soviet deployments of nuclear missiles in Cuba. The crisis lasted from 16 to 28 October 1962. The confrontation is widely considered the closest the Cold War came to escalating into full-scale nuclear war.

The Watergate scandal, or simply Watergate, was a political scandal in the United States involving the administration of President Richard Nixon. On June 17, 1972, operatives associated with Nixon's 1972 re-election campaign were caught burglarizing and planting listening devices in the Democratic National Committee headquarters at Washington, D.C.'s Watergate complex. Nixon's efforts to conceal his administration's involvement led to an impeachment process and his resignation in August 1974.

An asteroid is a minor planet—an object larger than a meteoroid that is neither a planet nor an identified comet—that orbits within the inner Solar System or is co-orbital with Jupiter. Asteroids are rocky, metallic, or icy bodies with no atmosphere, and are broadly classified into C-type (carbonaceous), M-type (metallic), or S-type (silicaceous). The size and shape of asteroids vary significantly, ranging from small rubble piles under a kilometer across to Ceres, a dwarf planet almost 1000 km in diameter. A body is classified as a comet, not an asteroid, if it shows a coma (tail) when warmed by solar radiation, although recent observations suggest a continuum between these types of bodies.

The Bundestag is the federal parliament of Germany. It is the only constitutional body in the country directly elected by the German people. The Bundestag was established by Title III of the Basic Law for the Federal Republic of Germany in 1949 as one of the legislative bodies of Germany, the other being the Bundesrat.

Space Shuttle Columbia (OV-102) was a Space Shuttle orbiter manufactured by Rockwell International and operated by NASA. Named after the first American ship to circumnavigate the globe, and the female personification of the United States, Columbia was the first of five Space Shuttle orbiters to fly in space, debuting the Space Shuttle launch vehicle on its maiden flight on April 12, 1981 and becoming the first spacecraft to be re-used after its first flight when it launched on STS-2 on November 12, 1981. As only the second full-scale orbiter to be manufactured after the Approach and Landing Test vehicle Enterprise, Columbia retained unique external and internal features compared with later orbiters, such as test instrumentation and distinctive black chines. In addition to a heavier aft fuselage and the retention of an internal airlock throughout its lifetime, these made Columbia the heaviest of the five spacefaring orbiters: around 1,000 kilograms heavier than Challenger and 3,600 kilograms heavier than Endeavour when originally constructed. Columbia also carried ejection seats based on those from the SR-71 during its first six flights until 1983, and from 1986 onwards carried an imaging pod on its vertical stabilizer.

RusAir Flight 9605 was a passenger flight which crashed near Petrozavodsk in the Republic of Karelia, Russia, on 20 June 2011 while attempting to land in thick fog.
