The present day Karagwe district in Tanzania, was part of a greater kingdom called the Karagwe Kingdom. The Karagwe kingdom was part of the many Great Lakes Kingdoms, in East Africa. Like many other Great Lakes kingdoms, the Karagwe people, known as Abanyambo, claim inheritance from the ancient Kitara empire, ruled by a dynasty known as the Bachwezi.
The Karagwe kingdom reached its apex during the 19th century. Archaeological evidence suggests that growth occurred during the early part of the 1800s. King Ndagara came to power around 1820 and ruled until 1853, at which time he was replaced by Rumanyika. The area has strong linguistic and historical ties to the Bugandan states to the north and to central African symbolic forms.
Near the end of the 18th century, Karagwe's prosperity became well known and traders came to barter salt, pepper, oranges, copper, and millet for local goods. Around 1800, beans and cooking bananas were introduced from Uganda. Early in the 1840s, Arabs arrived and trade flourished, especially the slave trade. The cowrie was introduced as hard currency and many new crops were introduced (e.g. sweet banana, tomatoes, maize, cassava, pawpaw, vegetables and citrus fruits).
