The Muslim Brotherhood in Libya announced on Saturday that it has formed a political party after six decades in the shadows of dictator Moammar Gadhafi's regime.
The Islamist group declared the creation of the Justice and Development Party in the absence of laws laying out a formal process for the establishment of political parties.
The Brotherhood's spokesman, Mohamed Gaair, said the group has representation in more than ۱۸ cities across the country, and that more than ۱,۴۰۰ members attended Friday's meeting in Tripoli to declare the formation of the political party.
They chose as party leader Mohamed Sowan, a native of the city of Misrata, which saw some of the worst fighting in the civil war that brought down Gadhafi and has since become distrustful of authority based elsewhere in the country.
Sowan worked as a hotel manager and was a political prisoner under the Gadhafi regime for eight years until ۲۰۰۶.
Gaair said that the Brotherhood has had a presence in Libya since ۱۹۴۹, but that many of its leaders were jailed under Gadhafi or exiled.
Several prominent former rebel leaders fighting to oust Gadhafi were associated with the movement, but the group does not have any officials in the transitional government.
Now, the Brotherhood is considered the most organized movement in Libya to have nationwide support. Supporters include wealthy businessmen who returned to the country after last year's civil war ended, opening up civil society groups and charitable funds throughout the war-ravaged country.
Gaair said the group aims to establish a just and developed society based on religious values.
"Our first main goal is to work on security and stability," he said. "We are still a new founded party, but we will work on the basis of Islamic principles and that doesn't mean the shallow meaning of religion most people think of like banning women from leaving home. This is not rational."
In October, Libya's Western-backed rulers said that Islamic law would be the main source of legislation.
The influence of the Brotherhood and related Islamist groups has surged following last year's Arab Spring uprisings. In Egypt, where the movement was founded in ۱۹۲۸, its affiliated political party has taken around half the seats in parliament.
Elections have swayed heavily in favor of Islamic movements in Tunisia and Morocco, as well. They are key to the opposition in Yemen and are playing a role in Syria's uprising. The Brotherhood's offshoot, Hamas, rules the Gaza Strip. Their political arm in Jordan, the Islamic Action Front, is the country's largest opposition group.
The pan-Arab Muslim Brotherhood, though, is not unified in its interpretation of Islamic law nor in how it should be applied. The groups also have separate funding mechanisms.
The Brotherhood also faces competition from other more hard-line Islamist groups including followers of the ultraconservative Salafi trend of Islam.
