With Clodius reduced in power and influence, the senate was stirring again, seeking to gain back some power from the three triumvirs. So in 56 BC a meeting was held at Luca in Cisalpine Gaul by the three men, determined to hold onto their privileged position.
The result of the meeting was that Pompey and Crassus stood for the consulship again and were elected - largely due to the fact that Crassus' son, who had been serving brilliantly under Caesar, was at no great distance from Rome with a returning legion.
Did Pompey and Crassus gain office in such way, then Caesar's part of the bargain was that the two new consuls extended his term in office in Gaul by another five years (until 49 BC).
