President William Howard Taft devoted a considerable portion of his First Annual Message to Congress (December 7, 1909) to the Liberian question, noting the close historical ties between the two countries that gave an opening for a wider intervention: In 1926, the Liberian government gave a concession to the American rubber company Firestone to start the world's largest rubber plantation at Harbel, Liberia.

The Krus and Greboe tribes remained highly reluctant to accept control from Monrovia, but they were not powerful enough to overcome a regime strongly supported by the United States Army and Navy.

[9] The rise of Charles Taylor's government, the Liberian Civil War, regional instability and human rights abuses interrupted the previously close relations between Liberia and the United States.

[2][12] Much of the Liberian-American tension from this period stems from the Liberian government's acknowledged support for the Revolutionary United Front, a rebel group in Sierra Leone and surrounding region.

[8] Due to intense pressure from the international community and the United States, along with Liberian civic organizations like the Women of Liberia Mass Action for Peace, Charles Taylor resigned his office on August 11, 2003.

On July 30, 2003, the United States proposed a UN Security Council draft resolution to authorize the deployment of a multi-national stabilization force.

USAID supports rule of law programs, establishing legal aid clinics and victim abuse centers, training judges and lawyers, community peace building and reconciliation efforts, and anti-corruption projects to promote transparency and accountability in public sector entities.

[17] On December 18, during its quarterly meeting, the Millennium Challenge Corporation (MCC) Board of Directors designated Liberia as newly eligible to develop a compact.

This decision acknowledges Liberia’s significant progress in improving its performance on the MCC scorecard and its dedication to advancing key economic and democratic governance reforms.
