Decimus Junius Silanus (consul)

Consul in 62 BC, husband of Servilia

Decimus Junius Silanus (107 – after 62 BC) was a consul of the Roman Republic. He may have been the son of Marcus Junius Silanus, consul in 109 BC. He was the stepfather of Marcus Junius Brutus, having married Brutus' mother, Servilia.

Born in 107 BC, Decimus Junius M. f. D. n. Silanus was the son of a Marcus Junius Silanus, presumably Decimus had an elder brother named Marcus, but he might have died young.

Silanus married Servilia, after her first husband died. Together they had four children, a son, Marcus Junius Silanus, and three daughters, Junia Prima, Junia Secunda, and Junia Tertia. Silanus may also have been the father of a Decimus Junius Silanus.

He was aedile in 70 BC, but he lost the election to be a consul of 63. He was successful the following year, and so in consequence of his being consul designatus was first asked for his opinion by Cicero in the debate in the senate on the punishment of the Catilinarian conspirators. At first he spoke in favor of "the supreme penalty" for the conspirators, but when Julius Caesar suggested life imprisonment, Silanus insisted that was what he had really meant. As such, it was left to Cato the Younger to force through the decision to actually execute them. He was consul in 62 with Lucius Licinius Murena. They proposed the lex Junia Licinia, which provided that a rogatio (a proposed law) must be promulgated three nundinae, or market intervals, before the people voted on it. It also confirmed the lex Caecilia Didia.
