1887 – The Rocky Mountains Park Act becomes law in Canada creating the nation's first national park, Banff National Park.

Banff National Park is Canada's oldest national park, established in 1885. Located in Alberta's Rocky Mountains, 110–180 kilometres (68–112 mi) west of Calgary, Banff encompasses 6,641 square kilometres (2,564 sq mi) of mountainous terrain, with many glaciers and ice fields, dense coniferous forest, and alpine landscapes. The Icefields Parkway extends from Lake Louise, connecting to Jasper National Park in the north. Provincial forests and Yoho National Park are neighbours to the west, while Kootenay National Park is located to the south and Kananaskis Country to the southeast. The main commercial centre of the park is the town of Banff, in the Bow River valley.

The Canadian Pacific Railway was instrumental in Banff's early years, building the Banff Springs Hotel and Chateau Lake Louise, and attracting tourists through extensive advertising. In the early 20th century, roads were built in Banff, at times by war internees from World War I, and through Great Depression-era public works projects. Since the 1960s, park accommodations have been open all year, with annual tourism visits to Banff increasing to over 5 million in the 1990s. Millions more pass through the park on the Trans-Canada Highway. As Banff has over three million visitors annually, the health of its ecosystem has been threatened. In the mid-1990s, Parks Canada responded by initiating a two-year study which resulted in management recommendations and new policies that aim to preserve ecological integrity.

Banff National Park has a subarctic climate with three ecoregions, including montane, subalpine, and alpine. The forests are dominated by Lodgepole pine at lower elevations and Engelmann spruce in higher ones below the treeline, above which is primarily rocks and ice. Mammal species such as the grizzly bear, cougar, wolverine, elk, bighorn sheep and moose are found, along with hundreds of bird species. Reptiles and amphibians are also found but only a limited number of species have been recorded. The mountains are formed from sedimentary rocks which were pushed east over newer rock strata, between 80 and 55 million years ago. Over the past few million years, glaciers have at times covered most of the park, but today are found only on the mountain slopes though they include the Columbia Icefield, the largest uninterrupted glacial mass in the Rockies. Erosion from water and ice have carved the mountains into their current shapes.

1894 Born: Edward VIII, King of the United Kingdom (d. 1972)

Edward VIII (Edward Albert Christian George Andrew Patrick David; 23 June 1894 – 28 May 1972) was King of the United Kingdom and the Dominions of the British Empire and Emperor of India from 20 January 1936 until his abdication in December of the same year.

Edward was born during the reign of his great-grandmother Queen Victoria as the eldest child of the Duke and Duchess of York, later King George V and Queen Mary. He was created Prince of Wales on his 16th birthday, seven weeks after his father succeeded as king. As a young man, Edward served in the British Army during the First World War and undertook several overseas tours on behalf of his father. While Prince of Wales, he engaged in a series of sexual affairs that worried both his father and then-British prime minister Stanley Baldwin.

Edward became king on his father's death. As king, he showed impatience with court protocol, and caused concern among politicians by his apparent disregard for established constitutional conventions. Only months into his reign, a constitutional crisis was caused by his proposal to marry Wallis Simpson, an American who had divorced her first husband and was seeking a divorce from her second. The prime ministers of the United Kingdom and the Dominions opposed the marriage, arguing a divorced woman with two living ex-husbands was politically and socially unacceptable as a prospective queen consort. Additionally, such a marriage would have conflicted with Edward's status as titular head of the Church of England, which, at the time, disapproved of remarriage after divorce if a former spouse was still alive. Edward knew the Baldwin government would resign if the marriage went ahead, which could have forced a general election and would have ruined his status as a politically neutral constitutional monarch. When it became apparent he could not marry Wallis and remain on the throne, he abdicated. He was succeeded by his younger brother, George VI. With a reign of 326 days, Edward is the shortest-reigning monarch of the United Kingdom.

After his abdication, Edward was created Duke of Windsor. He married Wallis in France on 3 June 1937, after her second divorce became final. Later that year, the couple toured Nazi Germany. During the Second World War, Edward was at first stationed with the British Military Mission to France, but after private accusations that he was a Nazi sympathizer, he was appointed Governor of the Bahamas. After the war, Edward spent the rest of his life in France. He and Wallis remained married until his death in 1972. Wallis died 14 years later.

1919 – Estonian War of Independence: The decisive defeat of the Baltische Landeswehr in the Battle of Cēsis; this date is celebrated as Victory Day in Estonia.

The Estonian War of Independence (Estonian: Vabadussõda, literally "Freedom War"), also known as the Estonian Liberation War, was a defensive campaign of the Estonian Army and its allies, most notably the White Russian Northwestern Army, Latvia, and the United Kingdom, against the Soviet Western Front offensive and the aggression of the Baltische Landeswehr. It was fought in connection with the Russian Civil War during 1918–1920. The campaign was the struggle of Estonia for its sovereignty in the aftermath of World War I. It resulted in a victory for the newly established state and was concluded in the Treaty of Tartu.
