To the student of political history, and to the English student above all others, the conversion of the Roman Republic into a military empire commands a peculiar interest. Notwithstanding many differences, the English and the Romans essentially resemble one another. The early Romans possessed the faculty of self-government beyond any people of whom we have historical knowledge, with the one exception of ourselves. In virtue of their temporal freedom, they became the most powerful nation in the known world; and their liberties perished only when Rome became the mistress of conquered races, to whom she was unable or unwilling to extend her privileges.
