A prominent Kurdish politician, Selahattin Demirtas, once helped Turkey’s leader come close to ending the decades-old conflict with Kurdish militants that has killed tens of thousands of people.

Today, Mr. Demirtas is in prison, where he has been for more than 20 months on 100 charges, including terrorism and insulting that same leader, President Recep Tayyip Erdogan. He has been barred from the mainstream news media.

Yet all of that did not stop him from running for the presidency in Turkey’s recent election — and finishing third. Now that Mr. Erdogan has won the June 24 election, the chances that Mr. Demirtas will be released from prison are dimming.

Mr. Erdogan is amassing power in a new presidential system — allowing him to exert control in nearly every aspect of public life — and has effectively sidelined those who challenge him. Mr. Demirtas and his supporters say the charges against him are political, aimed at crushing his pro-Kurdish Peoples’ Democratic Party, or H.D.P. That tactic seems to have failed, even as Mr. Demirtas’s own hopes have diminished.

The party cleared the 10 percent threshold needed to win a place in Parliament, securing 67 seats in the expanded 600-member legislature. The result represented the party’s third successive electoral success since 2015, when it first won seats in Parliament, and showed that Mr. Demirtas’s vision of peace and democracy in Turkey still resonates with Kurds, as well as with some liberals, young people and minority voters. “Under these circumstances it is a great success that H.D.P. has a place in Parliament,” he said in a message posted on Twitter the day after the election.

It was one in a series of notes passed along to his lawyers for posting, his only way of communicating regularly with supporters. “Whatever my circumstances are,” he added, “I want everybody to know that I will continue the struggle without being discouraged.” Members of the opposition alliance against Mr. Erdogan had called for the release of Mr. Demirtas, 45, a former human rights lawyer, but he faces potential life imprisonment if convicted of just some of the charges against him.

Mr. Erdogan has labeled the Peoples’ Democratic Party a separatist organization, called for a swift resolution to Mr. Demirtas’s trial and even suggested that he would sign the death penalty back into law if Parliament passed it. Every week, Mr. Demirtas’s wife, Basak, 41, travels the length of the country and back — about 2,000 miles — to talk to her husband through a window in the high-security prison at Edirne in western Turkey. Once a month, the family is allowed to meet in a room. Ms. Demirtas, a schoolteacher, limits her daughters, 12 and 14, to monthly visits because the trip is so grueling.

Childhood sweethearts, the couple grew up in the warren of small streets and ancient monuments of Sur, a neighborhood inside the old walled city of Diyarbakir. The imposing black basalt city walls that date from the Byzantine era encircle the old city like a massive fortress on a hill above the Tigris River. But the Sur neighborhood is more like an empty parking lot today. The houses have been razed, and the few mosques and historical buildings left are surrounded by stretches of rough ground. Mr. Erdogan came to power in 2002 offering to make peace with the insurgent Kurdistan Workers’ Party, which has been fighting the Turkish state for nearly three decades. He came close to achieving that with the help of Mr. Demirtas, whose activists worked as mediators with the insurgents. But in 2015 the peace talks broke down and both sides returned to violence.

For 18 months the Turkish government conducted punitive security operations in 30 Kurdish cities, including Diyarbakir, raising the conflict to a level of urban strife never seen before in Turkey. A United Nations report estimates that around 2,000 people were killed in that period, many of them civilians, while 355,000 Kurds were displaced. Ms. Demirtas described how government bombing would wake her family up in their apartment across town. “One night it was so bad I thought they were bombing all of Diyarbakir,” she said. “Can you imagine that we could hear it from 20 kilometers away?” The Turkish government has blamed Mr. Demirtas and his party for encouraging people to resist the government in the cities, along with the armed Kurdistan Workers’ Party. Mr. Demirtas and his followers insist that they espoused only peaceful, democratic means. They accuse the government of waging the military campaign because of the party’s surprising success at the polls. Mr. Demirtas was detained in October 2016.

Police officers came for him at 1:30 a.m., though he had spent the previous day alone in their apartment while his wife was at work. “I could not count them — there were 200 or more,” his wife said. “In this block, for 500 meters up to my sister’s house, it was all police, special forces with masks.” “I always say he was not detained,” she said. “Selahattin was kidnapped.”
