During the Cardassian Occupation of Bajor, he was a member of the Ornathia resistance cell. His brother was imprisoned at the Gallitep labor camp, and was one of the Bajorans freed when Shakaar Edon's resistance cell liberated the camp.
That year, he was sent by acting First Minister Winn Adami to capture Shakaar Edon, who refused to turn over soil reclamators to the government. Realizing these orders could lead to civil war, Lenaris instead accepted a truce with Shakaar, and rallied the Militia's support behind Shakaar's candidacy for First Minister. (DS9 episode: "Shakaar")
By 2376, Lenaris had reached the rank of general, and was one of the top officers within the Bajoran Militia. He was one of the signatories to Bajor's admittance into the Federation. (DS9 novel: Unity)
