MADRID — Iñaki Urdangarin, the brother-in-law of King Felipe VI of Spain, was sentenced to prison Friday in a business fraud case that represented a major embarrassment to the monarchy, even though the king’s sister, Princess Cristina, was found not guilty.

A court on the island of Majorca sentenced Urdangarin to six years and three months in prison, far less than the 19 1/2 years sought by the prosecution, for his business dealings relating to the disbursement of millions of dollars of public funds for sporting events.

In January 2016, Cristina became the first member of Spain’s royal family to stand trial in modern history, after the authorities began looking into Urdangarin’s business practices in 2011. The police raided the offices of his nonprofit foundation, the Nóos Institute, as part of an investigation initially prompted by huge cost overruns for the construction of a cycling track on Majorca.

Urdangarin — who was found guilty on counts including fraud, document falsification, tax evasion, and influence peddling — was among 18 defendants on trial. He and his business partners were accused of embezzling about 6 million euros, or $6.4 million, that had been distributed by regional officials for organizing sports events.

The princess was on the board of Nóos, and she and her husband owned a real estate company, Aizoon, that prosecutors claimed was used to channel illegal revenue from Nóos to undeclared bank accounts.
