Context_5 : Canada first came under British rule with the Treaty of Paris (1763) which ceded New France, of which Canada was a part, to the British Empire. Gradually, other territories, colonies, and provinces that were part of British North America would be added to Canada. The Royal Proclamation of 1763 enlarged the colony of Canada under the name of the Province of Quebec, which with the Constitutional Act 1791 became known as The Canadas. With the Act of Union 1840 Upper and Lower Canada were joined to become the United Province of Canada. Later, with Confederation in 1867, the British maritime colonies of New Brunswick and Nova Scotia were joined with the British colony of Canada to form the Dominion of Canada, which was subsequently divided into four provinces, Ontario, Quebec, New Brunswick, and Nova Scotia. A number of other British colonies, such as Newfoundland and British Columbia, and large territories such as Rupert's Land initially remained outside of the newly formed federation. Over time, the remaining colonies and territories within British North America came under the control of Canada until the current geographic extent of the country was reached when Newfoundland and Labrador joined Canada in 1949. Although confederation in 1867 led to an enlarged Dominion with increased autonomy over domestic affairs, Canada still remained a colony within the British Empire and was thus subordinate to the British Parliament until the enactment of the Statute of Westminster in 1931. This statute recognized Canada as an independent peer coequal with the United Kingdom, and thus provided the Parliament of Canada with legislative sovereignty over all federal matters except the power to change the constitutional laws of Canada which remained under the purview of the Parliament of the United Kingdom. Canada's final vestige of legal dependence on the United Kingdom was terminated in 1982 with the enactment of the Canada Act, subsequently providing Canada with full legal sovereignty completely independent of the United Kingdom. Context_6 : Liberty cuffs are a form of unauthorized personal decoration applied to the inside of the cuffs of military uniforms, which became popular in the United States Navy in the early 1900s and were imitated by other U.S. military branches starting around World War I.

Context_10 : Roberts Ice Piedmont ( ) is a large ice piedmont, 20 nautical miles (37 km) long in a north-south direction and 15 nautical miles (28 km) wide, lying to the north and northwest of Mount Calais and occupying most of the northeast corner of Alexander Island, Antarctica. It was first seen from a distance and roughly surveyed by the French Antarctic Expedition, 1908–10, under Charcot. It was photographed from the air by the British Graham Land Expedition (BGLE) on August 15, 1936, and roughly mapped from these photos. It was then named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1955 after Brian B. Roberts (1912–78), a British ornithologist, polar specialist and leading figure in the development of Antarctic nomenclature; ornithologist, BGLE, 1934–37; Secretary, United Kingdom Antarctic Place-names Committee, 1945-74. About six nunataks are situated within the Roberts Ice Piedmont, these are Hengist Nunatak (a separate nunatak) and the Horsa Nunataks (a group of about five nunataks). Both of these features are named after Saxon kings of England in the fifth century; however, they have no association or relation with Brian B. Roberts and the Roberts Ice Piedmont itself. fact_1 :  The Type 07 uniforms were first seen in late June, 2007 during a celebration ceremony for the 10th anniversary of the Transfer of sovereignty over Hong Kong. fact_2 : The transfer of sovereignty over Hong Kong from the United Kingdom to China, referred to as "the Handover" internationally or "the Return" in China, took place on 1 July 1997.
