Liberians started voting on Tuesday to elect a new president in a contest set to complete the country's first democratic transition of power in more than 70 years.
Voting opened at 8am after a campaign hailed for a vibrant and violence-free debate in the small West African nation, which suffered back-to-back civil wars from 1989 to 2003.
Africa's first female elected head of state, Ellen Johnson Sirleaf, is stepping aside after a maximum two six-year terms.
The country's 2.18 million registered voters are choosing from a crowded field of 20 presidential candidates - although just one of them is a woman - and also elect 73 seats to the lower chamber, House of Representatives.
"The future of the country is in your hands, no one is entitled to your vote, not because of party, ethnicity, religion or tribal affiliation," Ms Sirleaf, a co-winner of the 2011 Nobel Peace Prize, declared in a speech on Monday.
Among the frontrunners are footballing icon George Weah, incumbent vice president Joseph Boakai, longtime opposition figure Charles Brumskine and former Coca-Cola executive Alexander Cummings.
Also waiting in the wings with potentially significant vote share are telecoms tycoon Benoni Urey and former central bank governor Mills Jones.
Otis Wallace, who has two degrees but works as a security guard for a lack of other options, was first in line at a polling station on Water Street in Monrovia after arriving at 5am to get a spot.
"I feel Mr Weah can make a change," he said. "I feel marginalised by this government."
Farther down the line, Christmas Kamara, a market trader, said she felt betrayed by the government during the Ebola crisis that caused rioting in Westpoint.
"We need healthcare and hospitals," she told AFP. "Our people are dying because of the lack of hospitals."
The first official results are expected within 48 hours after voting closes at 6pm. If no candidate wins 50 per cent of the presidential vote, then a run-off of the top two contenders will be held on November 7 - an outcome analysts say is a near certainty.
"There is going to be a run-off, and that is most likely to be the parties that have gone to a run-off in the last two elections," Ibrahim Al Bakri Nyei, a Liberian political analyst at London's School of Oriental and African Studies (SOAS), told AFP.
Ms Sirleaf's Unity Party swept the vote in 2005 and 2011, results that Mr Weah's Congress for Democratic Change (CDC) contested in court.
Time for the 'chosen one'?
Back-to-back civil wars and the 2014-16 Ebola crisis have stunted growth and left Liberia among the world's poorest nations, while entrenched corruption has not been rooted out by the Sirleaf administration.
Dash Gamu, a teenage motorcycle taxi rider, said he would be voting for Mr Weah but was not familiar with his vice-presidential pick Jewel Howard-Taylor, the ex-wife of Liberian warlord Charles Taylor.
"He is the chosen one for this nation," he told AFP.
Mr Weah consistently captured the youth vote when he ran for president in 2005 and vice-president in 2011, but Mr Cummings has made inroads into his support.
A fifth of Liberia's registered voters are aged 18-22 and are less likely, analysts say, to vote along ethnic lines or to support candidates like Prince Johnson, a former rebel leader who maintains a strong following in northeastern Nimba county.
Regardless of the result, the international community is keen to see Liberia's history of coups, assassinations and exiled dictators shift to a more stable footing after 12 years of peace under Ms Sirleaf.
The election has been largely violence-free and the National Elections Commission expected the same on voting day, NEC spokesman Henry Flomo told AFP.
"We all must respect the outcome of the election as declared by the National Elections Commission," Ms Sirleaf warned in her speech on Monday.
Liberia's police and army are overseeing election security for the first time since the civil war following a handover from UN peacekeepers last year, and though underfunded have kept the peace during the campaign.
Electoral observers from regional body ECOWAS, the African Union, the European Union and the United States will all oversee the process.
