Which situation in the 1800s is the best example of a colonial protectorate?

One of the best examples of a colonial protectorate in the 1800s is British control over Egypt. Although Egypt was nominally an independent state, it was effectively governed by British officials who managed its finances and military, particularly after the British occupation began in 1882. This arrangement allowed Britain to exert influence over Egyptian affairs while maintaining a facade of local governance, highlighting the characteristics of a protectorate situation.
