19世紀末，正值葡萄牙共和運動興起，葡萄牙布拉幹薩皇朝提出咗粉紅地圖計劃，希望佔領葡屬安哥拉同同葡屬莫桑比克之間嘅英國殖民地（即係今日嘅贊比亞全境 同 今日津巴布韋部份領土），重向本國百姓加重徵稅，作為實行計劃嘅資金來源。
At the end of the 19th century, with the rise of the Portugal Republican Movement, the Bragança Dynasty of Portugal proposed the Pink Map Project, hoping to occupy Portuguese Angola and the United Kingdom colonies between Portuguese Mozambique (that is, all of today's Zambia and part of today's Zimbabwe), and re-impose heavy taxes on its own people as a source of funds for the implementation of the plan.
