What enabled the British Empire to really dominate the Age of Colonialism?

India, really. It was the heart of the Empire and the part that made sense of the rest of it. It was also the part that none of the other Empires of the period had any equivalent to. The extremely successful commercially-driven part of the Empire in East and South East Asia? Plenty of other European powers were at that game as well, and Britain didn't even have the biggest slice of it (the Netherlands did) even if it played its hand a lot better than everyone else. The quite literal colonies in Australia, Canada and so on? Siberia, Algeria and the Western United States all existed. The African colonies? Obviously matched and then some by others, and really only a few of them were ever of much importance, and even in then in one case (Egypt, which was never formally a colony, of course) purely because of India. The West Indies? That was a mixture right from the beginning and remains so in a tiny and lingering form (it still isn't quite over). So you need to consider India, the slow patchwork conquest of the entire subcontinent by the East India Company, and all of the factors that led to that, because that's the distinctive part.

Again… why?

The Industrial Revolution happening in Britain?
