Context paragraphs:
History of Newfoundland and Labrador: The first brief European contact with Newfoundland and Labrador came about 1000 AD when the Vikings briefly settled in L'Anse aux Meadows.  Around 1500 AD, European explorers and fishermen from England, Portugal, France, and Spain (mainly Basques) began exploration.  Fishing expeditions came seasonally; the first small permanent settlements appeared around 1630 AD.  Catholic-Protestant religious tensions were high but mellowed after 1860.  The British colony voted against joining Canada in 1869 and became an independent dominion in the early 20th century.  Fishing was always the dominant industry, but the economy collapsed in the Great Depression of the 1930s and the people voluntarily relinquished their independence to become a British colony again.  Prosperity and self-confidence returned during the Second World War, and after intense debate the people voted to join Canada in 1949.

Colony of Natal: The Colony of Natal was a British colony in south-eastern Africa.  It was proclaimed a British colony on 4 May 1843 after the British government had annexed the Boer Republic of Natalia, and on 31 May 1910 combined with three other colonies to form the Union of South Africa, as one of its provinces.  It is now the KwaZulu-Natal province of South Africa.

Cape Colony: The Cape of Good Hope, also known as the Cape Colony (Dutch: "Kaapkolonie" ), was a British colony in present-day South Africa and Namibia, named after the Cape of Good Hope.

The Dutch lost the colony to Britain following the 1795 Battle of Muizenberg, but had it returned following the 1802 Peace of Amiens.  It was re-occupied by the British following the Battle of Blaauwberg in 1806, and British possession affirmed with the Anglo-Dutch Treaty of 1814.

He became famous for championing human rights during the late nineteenth century, establishing the first free secondary school for poor children in British Guiana in 1894, serving as Mayor of British Guiana's capital city Georgetown, and authoring editorial columns for the British colony's influential newspapers "Echo" and "Outlook".

Several hundred thousand dollars in capital was raised during that time period for construction and modernization on the Gold Coast (British colony) through the stock market, and infrastructure metal deals were made with companies such as U.S. Steel.  In the beginning of Chappelle's business, he was reported to have made contracts with 82 tribal chiefs in Gold Coast, West Africa, for the exportation of gold, cocoa, rubber, and mahogany.  The money was to be used to develop 440 miles with the African Central Railroad and the West Coast Steam and Harbor Company, both African-American and African joint ventures.

Georgetown remained a separate municipality until 1871, when the United States Congress created a new consolidated government for the whole District of Columbia.  A separate act passed in 1895 specifically repealed Georgetown's remaining local ordinances and renamed Georgetown's streets to conform with those in the City of Washington.
