Founded in 1826 as Bytown and incorporated as "Ottawa" in 1855, the city has evolved into a political and technological centre of Canada. Its original boundaries were expanded through numerous minor annexations and ultimately replaced by a new city incorporation and major amalgamation in 2001 which significantly increased its land area. The name "Ottawa" is derived from the Algonquin word adawe, meaning "to trade". Initially an Irish and French Christian settlement, Ottawa has become a multicultural city with a diverse population.
