Cape Mesurado is a headland on the coast of Liberia near the capital Monrovia and the mouth of the Saint Paul River. It was named Cape Mesurado by Portuguese sailors in the 1560s. It is the promontory on which African American settlers established the city now called Monrovia on 25 April 1822.
There is a lighthouse on Cape Mesurado, located in the Mamba Point neighborhood of Monrovia and in the cape's northwestern portion, that was established in 1855. It is currently inactive, although the Liberian government is seeking financial assistance to restore and reactivate the lighthouse.
The year prior to the settlers' arrival, the American Colonization Society dispatched a representative, Dr. Eli Ayers, to purchase land farther north up the coast from Sierra Leone, where the settlers had previously landed at Sherbro Island but were experience a high death rate due to the island's swampy, unhealthy conditions. With the aid of Robert F. Stockton, a U.S. naval officer, Ayers sought out land to establish a new colony. Stockton led negotiations with leaders of the Dei and Bassa peoples who lived in the area of Cape Mesurado. At first, local tribal leaders such as King Peter were reluctant to surrender their peoples' land to the strangers, but were forcefully persuaded—some accounts claim at gun-point—to part with a "36 mile long and 3 mile wide" strip of coastal land for trade goods, supplies, weapons, and rum worth approximately $300.
The Cape Mesurado colony faced many of the same barriers to success as the previous colony at Sherbro Island: little supplies, as well as swampy and unhealthy conditions. There was also conflict with local tribes, who resented the now Americo-Liberian residents - who had been slaves or the children of former slaves in the United States before their emigration to Africa - trying to put an end to the slave trade. Led by Lott Carey and Elijah Johnson, the Americo-Liberians organized their own defense against local attacks and rejected British military assistance in exchange for hoisting the Union Jack on Cape Mesurado.
