His sentencing was scheduled for July 11.

The jury found that Mr. Trump had faked records to conceal the purpose of money given to his onetime fixer, Michael D. Cohen. The false records disguised the payments as ordinary legal expenses when in truth, Mr. Trump was reimbursing Mr. Cohen for a $130,000 hush-money deal the fixer struck with the porn star Stormy Daniels to silence her account of a sexual liaison with Mr. Trump.

The felony conviction calls for a sentence of up to four years behind bars, but Mr. Trump may never see the inside of a prison cell. He could receive probation when he is sentenced, and he is certain to appeal the verdict — meaning it may be years before the case is resolved. Still, the jury’s decision is an indelible moment in America’s history, concluding the only one of four criminal cases against Mr. Trump that was likely to go to trial before Election Day.

Here’s what to know:

• Trump can still be president: Nothing in the Constitution prevents a felon from running for president, or serving in the White House. Mr. Trump — who has long claimed the case against him is politically motivated — is expected to try to leverage the verdict to his advantage on the campaign trail, painting himself as the victim of a Democratic cabal. But the verdict ended Mr. Trump’s run of good fortune with criminal cases.

• Inside the courtroom: Mr. Trump showed little emotion as the verdict was read, shaking his head as the jury’s foreman recited “Guilty” 34 times. The recitation took less than two minutes, a sudden end that came at the end of the second day of deliberations — after the judge in the case said he was planning to send the jury home for the day. Here’s what it was like inside the courtroom.

• Celebration and outrage: Reaction to the historic verdict was immediate. A demonstrator outside the courthouse raised a large “Trump Convicted” sign, while others pumped their fists. Mr. Trump’s campaign emailed out a fund-raising appeal calling him a “political prisoner.” And President Biden’s campaign urged supporters not to sit idle, saying on social media that the only way to keep Mr. Trump out of the White House was by voting. Here’s how voters around the country greeted the verdict.

• A proud prosecutor: The Manhattan district attorney, Alvin L. Bragg, thanked the jury for convicting Mr. Trump, who he said had falsified business records to “conceal a scheme to corrupt the 2016 election.” He added, “There are many voices out there but the only voice that matters is the voice of the jury, and the jury has spoken.” Read an analysis of how prosecutors won the case.

• An 8-year odyssey: The first inkling of the crimes committed by Mr. Trump emerged eight years ago, with a tip to The Wall Street Journal about another hush-money deal: $150,000 to a Playboy model who said she’d had an affair with the man who was then on the cusp of the presidency. Read a reporter’s account of the efforts to untangle the story.

• Trump’s response: Mr. Trump appeared somber during brief remarks outside the courthouse, in which he repeated a litany of complaints about the case, including that the judge, Juan M. Merchan, was biased against him. “The real verdict is going to be Nov. 5, by the people,” he told reporters, without responding to a shouted question about why Americans should vote for a felon. This is what he had to say.

• The jury deliberated for roughly 10 hours: The jurors asked to again hear portions of testimony by Mr. Cohen and David Pecker, the former publisher of The National Enquirer, who prosecutors say was part of a conspiracy to suppress unflattering stories on Mr. Trump’s behalf during the 2016 campaign. Read about what the jury wanted to hear again.

• Dueling views of the case: A prosecutor from the Manhattan district attorney’s office, Joshua Steinglass, said in closing arguments that Mr. Trump had tried to “hoodwink the American voter” Todd Blanche, a lawyer for Mr. Trump, told jurors the case hinged on the testimony of Mr. Cohen, whom he called “the greatest liar of all time.”
