Ultimately, jurors found Manafort guilty of eight of the 18 charges he faced: two counts of bank fraud, five counts of tax fraud and one count of failing to declare a foreign bank account.
Prosecutors alleged during his trial that Manafort used offshore bank accounts to hide tens of millions of dollars from Ukrainian politicians from the Internal Revenue Service.
Manafort also still faces sentencing in the District of Columbia in a separate case related to illegal lobbying.
While prosecutors had not recommended a specific sentence, they had cited federal sentencing guidelines that called for 19-1/2 to 24 years in prison. Nevertheless, Ellis said that aside from his crimes, Manafort has led an "otherwise blameless life" and that he had a good relationship with others.
Defense lawyers had asked Ellis to sentence Manafort to between 4-1/4 and 5-1/4 years in prison, writing in their sentencing memo that Mueller's "attempt to vilify Mr. Manafort as a lifelong and irredeemable felon is beyond the pale and grossly overstates the facts before this court".
He is still facing additional years in prison from another case: After his conviction in Virginia, Manafort pleaded guilty in Washington to foreign lobbying violations and witness tampering as part of a plea deal with prosecutors.
In a filing with the judge, they said Manafort is "truly remorseful" and is in poor health after spending the past nine months in prison. Even Ellis at the outset of the case speculated that prosecutors' true motive in prosecuting Manafort was to pressure him to provide evidence against Trump.
"To say I have been humiliated and ashamed would be a gross understatement", Manafort, who opted not to testify during his trial, told the court. "My life -personally and professionally-is in shambles".
Manafort's decisions, Mueller's team said, "were his own and his efforts at misdirection are further proof that he has not accepted responsibility for his criminal conduct".

He says the threat of more tornadoes will continue for several hours as the storm system races toward the Atlantic seaboard. Large-scale search and rescue operations have been launched in Lee County, where officials reported multiple injuries.
Mueller's team issued a scathing rebuttal, stating that Manafort had breached a plea agreement reached with the government and lied repeatedly to the Federal Bureau of Investigation and the Special Counsel's office.
"The last two years have been the most hard years for my family and I", Manafort said inside the Eastern District of Virginia courtroom.
The judge has used hearings in Manafort's case previously to inject politics into the proceedings.
Prosecutors add that Manafort was not forthcoming with earlier investigators.
His sentencing marks a spectacular downfall for a high-rolling Republican political guru who advised U.S. presidents, including Mr Trump, and foreign leaders.
Manafort served as Mr Trump's campaign chairman from March to August of 2016, before being replaced by Steve Bannon and Kellyanne Conway.
For their part, Manafort's lawyers seek mercy for a man once considered one of America's premier political consultants, advising four USA presidents and working around the world.
Manafort, they argued in court papers on Tuesday, "blames everyone from the special counsel's office to his Ukrainian clients for his own criminal choices".
In the case in Virginia, Judge Ellis showed some antagonism towards Mueller's prosecutors.
