Roberts was incapacitated by illness from 1875 until early 1876, Vice President Anthony W. Gardiner served as acting president. In the 1860s and 1870s, escalating economic difficulties weakened Monrovia's dominance over the coastal indigenous populations, leading to several violent conflicts. Conditions worsened following Roberts's second presidency, as the cost of imports was far greater than the income generated by exports of coffee, rice, palm oil, sugar cane, camwood, and timber. Inheritance and legacy Roberts died on February 24, 1876, less than two months after his final term as president ended. He was buried in Palm Grove Cemetery in Monrovia. In his will, he left $10,000 and his estate to the educational system of Liberia. Today, Liberia's main airport, Roberts International Airport, as well as the town of Robertsport and Roberts Street in Monrovia are named in his honor. His face is depicted on the Liberian ten dollar bill, introduced in 2000, and the old five dollar bill in circulation between 1989 and 1999. His birthday, March 15, is a national holiday in Liberia.
