The four Caliphs who ruled after prophet Muhammad death came to power through election. The election system was that the group of Muslim leaders (who are recognized with their sincerity and devotion to Islam and Muslims) select one and then the people agree on him by what is called "Mobai'a". If accepted by the majority, then he be the Caliph and all Muslims, who agreed and who didn't, will be supporting him.
There is no Muslim community that believes the position of Caliph should be a democratically elected leader like a President. Conversely, the SUNNI MUSLIMS argue that educated elders, representing the different sections of the community, should elect the Caliph by majority vote. However, following the ascension of Caliph Omar to power without such a vote, the Sunnis abandoned a formal voting mechanism.
SUNNI ISLAM believed that any Muslim could become Caliph if he was a good community leader; heredity was not terribly important.
They believed that the caliph should always be a relative of the prophet.
The belief that the Caliph can be any righteous Muslim is primarily associated with Sunni Islam. Sunni Muslims hold that leadership should be based on consensus and the capability of the individual, rather than lineage or specific family ties, as seen in the Shia tradition. This perspective emphasizes the importance of the community in selecting a leader who embodies the qualities of righteousness and piety.

The second caliph is Abu Jafar :)
After the death of the Prophet (SAW), Hazrat Abu Bakr Siddique (RAU) was chosen the Muslim Ruler. His title was 'The Caliph of the Rasool'. All the subsequent Caliphs were called Ameer-ul-Momineen. The title is generally called 'Caliph'.

A good caliph in the Muslim government needs to rule with authority.
The caliph, as the political and religious leader of the Islamic community, had several important religious duties. These included upholding and enforcing Sharia law, ensuring the proper practice of Islamic rituals and teachings, and promoting the welfare of the Muslim community. The caliph was also responsible for leading prayers, particularly the Friday congregational prayers, and overseeing the collection and distribution of zakat (almsgiving) to support the needy. Additionally, the caliph played a key role in maintaining unity within the Muslim Ummah and safeguarding the faith against internal and external threats.
Caliph refers to a Muslim civil and religious ruler, widely viewed as the successor of Muhammad.
