Gebre Mesqel Lalibela
Lalibela, regnal name Gebre Meskel( 1162 – 1221) was Emperor of Ethiopia of the Zagwe dynasty, reigning from 1181 to 1221.
According to Taddesse Tamrat, he was the son of Jan Seyum and brother of Kedus Harbe.
Perhaps the most well- known of the Zagwe monarchs, the namesake monolithic churches of Lalibela are attributed to his reign, although recent scholarship has suggested origins as early as the late Aksumite period, with the complex reaching its present form during his time.
He is venerated as a saint by the Orthodox Tewahedo churches.
King Lalibela was born at either Adefa or Roha( it was later named Lalibela after him) in Bugna in 1162 AD.
He was given the name" Lalibela", meaning" the bees recognise his sovereignty" in Old Agaw, due to a swarm of bees said to have surrounded him at his birth, which his mother took as a sign of his future reign as Emperor of Ethiopia.
Tradition states that he went into exile due to the hostility of his uncle Tatadim and his brother king Kedus Harbe, and was almost poisoned to death by his half- sister.
Because Lalibela came to power during his brother's lifetime, Taddesse Tamrat suspects that he came to power by force of arms.
Lalibela is said to have seen Jerusalem in a vision and then attempted to build a new Jerusalem as his capital in response to the capture of old Jerusalem by Muslims in 1187.
As such, many features of the town of Lalibela have Biblical names including the town's river, known as the River Jordan.
The city remained the capital of Ethiopia from the late 12th century and into the 13th century.
Details about the construction of his 11 monolithic churches at Lalibela have been lost.
The later" Gadla Lalibela", a hagiography of the king, states that he carved these churches out of stone with only the help of angels.
According to the narrative of the Portuguese embassy to Ethiopia in 1520- 6, written down by Father Francisco Álvares and published 1540, the Lalibelian priests claimed that the churches took 24 years to construct, and that they were made by white men.
They said that King Lalibela ordered this to be done.
His chief queen was Masqal Kibra, about whom a few traditions have survived.
She induced Abuna Mikael to make her brother Hirun bishop, and a few years later the Abuna left Ethiopia for Egypt, complaining that Hirun had usurped his authority.
Another tradition states that she convinced king Lalibela abdicate in favor of his nephew Na'akueto La'ab, but after 18 months of his nephew's misrule she convinced Lalibela to resume the throne.
Taddesse Tamrat suspects that the end of Lalibela's rule was not actually this amiable, and argues that this tradition masks a brief usurpation of Na'akueto La'ab, whose reign was ended by Lalibela's son, Yetbarak.
Getachew Mekonnen credits her with having one of the rock- hewn churches, Bet Abba Libanos, built as a memorial for Lalibela after his death.
Although little written material concerning the other Zagwe kings survives, a sizeable quantity concerning Lalibela's reign remains, besides the" Gadla Lalibela".
An embassy from the Patriarch of Alexandria visited Lalibela's court around 1210, and have left an account of him, and Na'akueto La'ab and Yetbarak.
The Italian scholar Carlo Conti Rossini has also edited and published the several land grants that survive from his reign.

According to Taddesse Tamrat, he was the son of Jan Seyum, the brother of Tatadim.
Some authorities date his reign to the years 1079–1119.

Na'akueto La'ab
Na'akueto La'ab was "negus" of Ethiopia, and a member of the Zagwe dynasty.
According to Taddesse Tamrat, he was the son of Kedus Harbe.
Richard Pankhurst credits him with the creation of the church located in a cave a half-day's journey from the town of Lalibela.
According to a manuscript Pedro Páez and Manuel de Almeida saw at Axum, Na'akueto La'ab ruled for 40 years, a suspiciously round number.
A "Gadla" or hagiography of Na'akueto La'ab exists, in a manuscript written in the 17th century.
According to Huntingford, it documents that Zagwe power had extended into Gojjam, and credits the king with building two churches: one at Sewa'a "which is said to have been called Wagra Sehin ('mountain of incense') '
among Celestrial', and Ashetan or Asheten 'among Terrestrials'", which Huntingford identifies with an existing church named Ashetan Maryam, a monolithic structure located a few kilometers east of Lalibela; the other in the land of Qoqhena, which was given a "tabot" from a desecrated church dedicated to Istifanos.
Tradition states that queen Masqal Kibra convinced her husband, King Lalibela, to abdicate in favor of Na'akueto La'ab, but 18 months later when the young king's soldiers appropriated a poor farmer's only cow for the king's dinner table, she convinced Lalibela to resume the throne.
Taddesse Tamrat suspects that the end of Lalibela's rule was not in truth this peaceful.
He argues that this tradition masks a brief period when Na'akueto La'ab "was no doubt a rallying point for disaffected elements in the country, and although kept under close watch managed to usurp the throne for a brief period until Yetbarak managed to take his father's throne."
