Julius Caesar changed world history by inaugurating the transformation of the Roman Republic into the Roman Empire. This themed volume of PLLS handles the important and controversial problem of Caesar's own attitudes to 'liberty' and 'autocracy'. It contains revised, annotated and sometimes expanded versions of papers delivered at the Seventh Annual Langford Conference at Florida State University, along with one supplementary contribution and English translations of two papers originally published in Italian. The contributors constitute a distinguished international group of ancient historians.
