A colonial empire is a collective of territories (often called colonies), either contiguous with the imperial center or located overseas, settled by the population of a certain state and governed by that state.[1]
Before the expansion of early modern European powers, other empires had conquered and colonized territories, such as the Roman Empire in Europe, North Africa and Western Asia. Modern colonial empires first emerged with a race of exploration between the then most advanced European maritime powers, Portugal and Spain, during the 15th century.[2] The initial impulse behind these dispersed maritime empires and those that followed was trade, driven by the new ideas and the capitalism that grew out of the European Renaissance. Agreements were also made to divide the world up between them in 1479, 1493, and 1494. European imperialism was born out of competition between European Christians and Ottoman Muslims, the latter of which rose up quickly in the 14th century and forced the Spanish and Portuguese to seek new trade routes to India, and to a lesser extent, China.
Throughout the 19th and early 20th century, by virtue of its technological and maritime supremacy, the British Empire steadily expanded to become by far the largest empire in history; at its height ruling over a quarter of the Earth's land area and 24% of the population. Britain's role as a global hegemon during this time ushered in a century of "British Peace", lasting from the end of the French Revolutionary and Napoleonic Wars to the start of World War I. During the New Imperialism, Italy and Germany also built their colonial empires in Africa.
New Zealand itself a colony that gradually increased its independence in 1907, 1947 and 1986, was tasked with the government of multiple other British colonies and territories and the mandate of Samoa. It was also nominal co-trustee of the mandate of Nauru. The remaining non-self-governing New Zealand territory is Tokelau.
The South-West Africa mandate was governed by the Union of South Africa, that itself a colony that gradually increased its independence in 1910, 1931 and 1961.

^During the reign of Philip V of Borbon, an intense diplomatic and military activity was developed with which the recovery of a significant Spanish presence in Italy was achieved. He placed several of his sons as independent sovereigns in different territories, such as the Duchy of Parma and especially the Kingdom of Naples, where the spanish House of Bourbon-Two Sicilies and House of Bourbon-Parma ruled until 1860.

^The dependencies of Norway are uninhabited, thus as end date is taken the latest date of full Norwegian sovereignty extension to such territory, instead of the date of decolonization or integration in the administrative structures of the mainland.
