Nicolas Sarkozy has become the first former French president to go to prison, after starting a five-year sentence for conspiring to finance his election campaign with money from the late Libyan dictator Muammar Gaddafi.
Since the time of World War II collaborationist leader Philippe Pétain, who was imprisoned for treason in 1945, no former French leader had ended up behind bars.
Sarkozy, who was president from 2007 to 2012, has appealed his sentence at La Santé prison, where he will remain in a cell measuring about 9 square meters in the prison's isolation section.
More than 100 people gathered outside the prison as his 28-year-old son, Louis, appealed for “support.” His other son, Pierre, asked for a message of love, “nothing else, please.”
The 70-year-old arrived at the entrance to the 19th-century prison in the Montparnasse district, south of the Seine River, at 9:40 a.m. under tight security. He continues to insist on his innocence in the highly controversial Libyan money case.
Sarkozy has stated that he does not want special treatment at the notorious La Santé prison, although he has been placed in the isolation section for security reasons, as other prisoners are often drug traffickers or convicted of terrorist offenses.
Besides Philippe Pétain, the only French head of state to be imprisoned was King Louis XVI, before being executed in January 1793.
Inside his cell he will have a toilet, shower, desk and a small television. He will be allowed one hour a day for physical exercise.

Late last week he was received at the Élysée Palace by President Emmanuel Macron, who told reporters on Monday: "It was normal on a human level to acknowledge one of my predecessors in that context."
In another sign of official support for the former president, Justice Minister Gérald Darmanin said he would visit him in prison as part of his duty to ensure Sarkozy's protection and the proper functioning of the institution. "I cannot be insensitive to a man's concern," he added.
Before arriving at La Santé prison, Sarkozy gave several media interviews, telling the newspaper La Tribune: "I am not afraid of prison. I will hold my head high, even at the prison gate."
Sarkozy has always denied doing anything wrong in a case that includes allegations that his 2007 presidential campaign was financed by millions of euros from Libya.
The former center-right leader was acquitted of personally receiving the money, but was convicted of criminal collusion with two of his close aides, Brice Hortefeux and Claude Guéant, to talk to Libyans about secret campaign financing.
The two men had meetings with Gaddafi's intelligence chief and his brother-in-law in 2005, in a meeting organized by a Franco-Lebanese intermediary named Ziad Tiakeddine, who died shortly before Sarkozy's conviction.
While he has filed an appeal, Sarkozy is still considered innocent, but has been asked to go to prison due to the "exceptional importance of the facts."
Sarkozy said he will take two books with him to prison: a biography of Jesus and The Count of Monte Cristo, the story of a man who is unjustly imprisoned and escapes to take revenge on his persecutors.
As for the first book, Jean-Christian Petitfils' "Jésus" published in 2011 offers a well-documented portrait of the life of Christ. Petitfils relies on historical sources and research to build a picture that avoids purely religious narratives.
Again, a straightforward choice in symbolism, but perhaps intentional to balance any desire for revenge that may be aroused by Dantès…
