Why did the French colonial empire cease to exist? Why the development of Western countries has become incompatible with the preservation of the colonial system

The French colonial empire ceased to exist in 1848 under the wave of the Great French Revolution. The fact is that earlier, during the war of 1792 – 1815, France lost a huge part of its colonies, all of them were captured by Great Britain.
The development of Western countries has become incompatible with the preservation of the colonial system because:
1) The peoples of the colonial countries intensified the struggle for their liberation.
2) The population of these countries no longer wanted to be second-class people. The liberation struggle of the colonial countries significantly hindered the development of Western countries,
