Senghor and Keïta both ruled their countries at the time of the split from the Mali Federation and for a number of years: Senghor was president of Senegal from 1960 until 1980 and Keïta from 1960 until 1968. Senghor suffered some domestic challenges after the split from the Mali Federation but after an armed fight between his supporters and those of Mamadou Dia's supporters in 1962, he had largely consolidated his rule. Senghor became very wary of unification efforts after the failed experiment and despite attempts to create other federations in West Africa and with Senegal's neighbors, Senghor often restrained these efforts and they only progressed after his rule. In addition, as the first failed unification experiment in Africa, the Mali Federation served as a lesson in future attempts at unification throughout the continent. Keïta became more assertive with pushing his ideology after the collapse of the federation and refused diplomatic relations with Senegal for many years. Nonetheless, Mali under Keïta still pursued the goal of West African unity but did so in a variety of different international connections. The railroad was reopened on 22 June 1963 and Senghor and Keïta embraced at the border.
