Huge expansion - Britain now the dominant world power. 'Discovery' Aust. 1770. 19C Scramble for Africa. Wealth flooded in from colonies. Sun never set. Canada, West Indies, Malta & Cyrpus in Med, Egypt, Sudan, Ghana, Nigeria, Rhodesia, Somalia & Botswana, & control of Suez canal added to Yemen & Oman & most importantly Indian Raj (India, Pakistan & Bangladesh) after Sepoy's Revolt 1858. + Hong Kong. BUT ppl & even politicians fairly disconnected from empire (after all, they couldn't vote). Viewed more in eco terms than moral terms
