During the 18th century, Europeans explored and colonized much of the world. French explorer Antoine de Bougainville led an expedition around the globe in 1766. Britain's victory in exploring the Pacific under Captain Cook expanded both scientific knowledge and British national pride. However, European empires relied on force and economic interests rather than internal unity. Napoleon later assumed a similar imperial role in Europe to the previous Holy Roman Empire. By the late 18th century, European maritime power extended around the globe through settlements in Australia, New Zealand, and growing influence over China.
