Many places which were once in the former British Empire were named after the British monarch who reigned over it for the greater part of its most dominant period, Queen Victoria.
During the process of Confederation, "Victorialand" and "Victorialia" were among the alternative suggestions to Canada as to what the name of the new Dominion should be.
[1][2] Note: this is only a small sample of the hundreds of locations in the United Kingdom with the name 'Victoria'.
Burma, Hong Kong, Ireland and Zimbabwe were within the British Empire at the time many of the listed places were named.
Hong Kong and Zimbabwe stopped being members of the Commonwealth of Nations in 1997 and 2003, respectively.
