What reasons can explain the success of the Europeans in the conquest of colonies?

It would be correct to mention here the fact that the European countries were much more developed than the peoples and territories that they conquered and made their colonies. Europeans were more organized, well-armed and were able to subjugate other peoples without any problems. In addition, they established their power there and, although shamelessly plundered these territories, they nevertheless developed the industry and partially the economy of these countries. Also, the conquered territories offered practically no resistance.
