On July 26, 1847, the settlers severed formal ties with the American Colonization Society and declared Liberia an independent sovereign state. It became West Africa’s oldest republic. The Liberian Declaration of Independence was drafted in English, mirroring the rhetorical cadences of Thomas Jefferson:
"We, the people of the Republic of Liberia, were originally inhabitants of the United States of North America. In some parts of that country, we were debarred by law from all the rights and privileges of men..."
The 1847 Constitution codified English as the sole language of statecraft, diplomacy, commerce, and the judiciary. Americo-Liberians constituted less than 5% of the overall population, yet they exercised total control over the state apparatus. For more than a century, through the rule of the True Whig Party from 1878 to 1980, the ruling minority enforced English as the prerequisite for civic participation.
This political hegemony created a strict social hierarchy. To access civil service jobs, run for office, or obtain title deeds for ancestral land, indigenous populations had to assimilate into the English-speaking coastal order. Schooling was conducted exclusively in English. Traditional oral languages were pushed to the margins of formal public life, cementing English as both an instrument of governance and a gatekeeper of social mobility.
