How far west did British territory exist?

British territory in North America extended to the Pacific Coast during the 19th century, particularly after the Oregon Treaty of 1846, which established the border between British North America (now Canada) and the United States at the 49th parallel. Prior to this, British claims stretched as far west as the Pacific Ocean, encompassing regions like British Columbia. However, the British Empire's global territories spanned various continents, including regions in Asia, Africa, and the Caribbean, making its reach far greater than just North America.
