What is the exact number of countries ruled by britishers?

There is no exact number of countries that were historically ruled by the British, as British colonial rule spanned various territories and time periods. At its height, the British Empire included colonies, protectorates, and territories across continents, totaling around 57 countries today that were at some point under British control. The impact of British colonialism can still be seen in many of these nations through language, legal systems, and cultural influences.
