Former president of the United States, George HW Bush, has died at the age of 94.
Family spokesman Jim McGrath said he had died shortly after 10pm on Friday US time, about eight months after the death of his wife, Barbara Bush.
The nation's 41st president served from 1989 to 1993, and eight years later watched his son George W Bush became the 43rd president.
The elder Mr Bush saw his popularity swell with the United States' success in the Gulf War in 1991, only to watch it evaporate in a brief but deep recession.
The Republican was defeated in his bid for a second term by Democrat Bill Clinton.
Mr Bush had also been a World War II hero, Texas congressman, CIA director and Ronald Reagan's vice president.
Only one other US president, John Adams, had a son who also became president.
George W Bush said his father was a "man of the highest character and the best dad a son or daughter could ask for".
In a statement, he added: "The entire Bush family is deeply grateful for 41's life and love, for the compassion of those who have cared and prayed for Dad, and for the condolences of our friends and fellow citizens."
Barack Obama, the 44th president of the US, said America had "lost a patriot and humble servant".
He said: "While our hearts are heavy today, they are also filled with gratitude. Our thoughts are with the entire Bush family tonight - and all who were inspired by George and Barbara's example."
In a statement, he added: "George HW Bush's life is a testament to the notion that public service is a noble, joyous calling. And he did tremendous good along the journey... It's a legacy of service that may never be matched, even though he'd want all of us to try."
Current US president Donald Trump said Mr Bush had "inspired generations of his fellow Americans to public service".
In a joint statement with wife Melania, he said: "Through his essential authenticity, disarming wit, and unwavering commitment to faith, family and country, President Bush inspired generations of his fellow Americans to public service - to be, in his words, "a thousand points of light" illuminating the greatness, hope and opportunity of America to the world.
"President Bush always found a way to set the bar higher."
He added: "Along with his full life of service to country, we will remember President Bush for his devotion to family - especially the love of his life, Barbara.
"His example lives on, and will continue to stir future Americans to pursue a greater cause."
James A Baker III, Mr Bush's former secretary of state and longtime confidant, said his friend's legacy "will be forever etched in the history of America and the world".
He noted Mr Bush's "lifelong record of selfless patriotic service to our nation", and said that in each of his roles had had "led with strength, integrity, compassion and humility - characteristics that define a truly great man and effective leader".
"With a singularly unique consistency, he always demonstrated these traits, whether on the global stage or interacting with people in his everyday life," he added. "His passion was a deep love of family and our country."
