The Syriac Orthodox Patriarch of Antioch ܦܛܪܝܪܟܐ ܕܐܢܛܝܘܟܝܐ is the head of the Syriac Orthodox Church of Antioch (Syriac: ܥܺܕܬܳܐ ܣܽܘ̣ܪܝܳܝܬܳܐ ܬܪܺܝܨܰܬ ܫܽܘ̣ܒ̣ܚܳܐ). He is the Head of the Holy Synod of the Syriac Orthodox Church, the highest authority of Syriac Orthodox Church.
The position of the Patriarch of Antioch was established and first held by St. Peter the Apostle(Syriac: ܫܸܡܥܘܿܢ ܟܹ݁ܐܦ݂ܵܐ "Šemʿōn Kēp̄ā"). The Patriarch sits on the Holy Apostolic See at Antioch. The Patriarchate of Antioch is part of the Pentarchy of the Christian Church. He is the Bishop of Antioch, and considered as Primus Inter Pares or First Among the Equals/Bishops. 
History of the Patriarchate.
The Church of Antioch was established by St. Peter in AD 32.
When St. Peter left Antioch, to go to Rome (where he would establish the Church of Rome and later die), he appointed St. Evodius as the Patriarch. St. Evodius was succeeded by St. Ignatius, who was the first to describe the church as "Catholic" meaning "Universal". 
During the Synod of Nicaea, the Bishop of Antioch became one of the Patriarchs of the Pentarchy(along with fellow Patriarchate of Alexandria). After the Council at Chalcedon, Christianity split into the Catholics and the Oriental Orthodox, thus splitting the Church of Antioch. The Patriarch of Antioch and Pope of Alexandria were leading the Oriental Orthodox, and the Patriarch of Constantinople and the Pope of Rome were leading the Catholic Church.
St. Severus, the Patriarch of Antioch, was exiled to Egypt by the Emperor of the Byzantine Empire for following the Oriental Orthodox Church. The Catholic group of the Church of Antioch(later Greek Orthodox Church of Antioch), accepted the new Patriarch, appointed by the Pope of Rome, as their new Patriarch, after the exile of St. Severus. The Syriac Orthodox Church, or the Oriental Orthodox group of the Church of Antioch, continued to accept St. Severus as the Patriarch until his death in AD 538.
In AD 518 the Patriarchate was forced to flee from Antioch and it continues move from place to place until it moved to Dayro d-Mor Hanayo(Kurkmo Dayro, or Deir az-Za'faran), in Mardin, Turkey in 1106.
By AD 544, the Syriac Orthodox Church had only three bishops remaining. During this time, Fr. Jacob a priest, traveled to Constantinople, to ask Empress Theodora's(who was a Miaphisite herself), the Daughter of a Syriac Orthodox priest, consent to be ordained as a bishop. He was ordained as Mor Jacob Baradeus (Mor Ya'qub Burdono ܝܥܩܘܒ ܒܘܪܕܥܝܐ), by Pope Theodosius I, Pope of Alexandria and he traveled to many places to revive the Syriac Orthodox Church. He managed to consecrate 27 bishops, and hundreds of priests and deacons for the church. He led the consecration of Mor Segius of Tella as the Patriarch of Antioch(first Patriarch of the independent Syriac Orthodox Church) in 544. It is after this saint that the Syriac Orthodox Church in India gets the name "Jacobite"(Jacobite Syrian Christian Church) He revived the Miaphisite belief in the Church of Antioch throughout persecution.
The Syriac Orthodox Church continued to be persecuted under the Arabs, Mongols, Crusaders, Mamluks, and Ottomans.
During 1915 (known as the Sayfo/ܣܝܦ or "the year of the sword" in Syriac), more than 250,000 Syriac Orthodox Christians in the Middle East were wiped out by the Ottoman Empire. Many Syriac Orthodox Villages were emptied, and historical monasteries and churches were destroyed.
During World War I, the Patriarchate was again forced to flee by the Ottoman Empire and the patriarchate was forced to flee to Homs, Syria in 1953, and later, Damascus, in 1957.
The Syriac Orthodox Church continues to grow to this day under the Patriarchate. The Syriac Orthodox Church, along with the other Oriental Orthodox Churches, is now in sacramental cooperation with the Catholic Church, and is working on a communion with the Eastern Orthodox Church and the Catholic Church.
