Kru people

The Kru are an ethnic group who live in interior of Liberia. Their history is one marked by a strong sense of ethnicity and resistance to occupation. In 1856 when part of Liberia was still known as the independent Republic of Maryland, the Kru along with the Grebo resisted Maryland settlers' efforts to control their trade. They were also infamous amongst early European slave raiders as being especially averse to capture.
They are distinct from the Krumen (sometimes called Kru), a subgroup of the Grebo who live along the coast.
Their reputation was such that their value as slaves was less than that of other African peoples, because they would so frequently attempt to escape or to take their own lives upon being captured.[1]
Kru is one of the many ethnic groups in Liberia, comprising 7% of the population. It is also one of the main languages spoken. The Kru are one of the three main indigenous group players in Liberia's socio-political activities along with the Krahn and Mano.
Notable ethnic Krus include former soccer star George Weah and Christian Evangelist Samuel Morris who was originally known as Kaboo.[2] Liberian President Ellen Johnson Sirleaf is of mixed Kru, Gola, and German ancestry.[3][4] Mary Broh, the current mayor of Monrovia, is of mixed Kru and Bassa ancestry.
