In 65 BC the Roman censor Marcus Licinius Crassus argued before the Roman Senate that Rome should annex Ptolemaic Egypt, but his proposed bill and the similar bill of tribune Servilius Rullus in 63 BC were rejected. Ptolemy XII responded to the threat of possible annexation by offering remuneration and lavish gifts to powerful Roman statesmen, such as Pompey during his campaign against Mithridates VI of Pontus, and eventually Julius Caesar after he became Roman consul in 59 BC. However, Ptolemy XII's profligate behavior bankrupted him, and he was forced to acquire loans from the Roman banker Gaius Rabirius Postumus.
