disagreements over who leads the church
The Orthodox Church was founded by Jesus Himself in the year 33 AD, on the Day of Pentecost. According to Orthodox Christian beliefs, the Orthodox Church has always existed from the beginning of time (called the Church Triumphant) but the physical church on earth (called the Church Militant) was established in Jerusalem in 33 AD and continues to exist to this day without any changes to its dogmas and beliefs. From the Orthodox perspective, both the Orthodox and Catholics started at the same time, in the year 33 AD, when there was no such thing as Orthodox and Catholic, and there was only the universal Christian Church. So they both shared a common foundation for the first 1,000 years of their history. However, after that time, difference arose that led to the Great Schism of 1054 AD. This caused a split in the universal Church, which resulted in the formation of an Orthodox East and a Latin West. The Orthodox Church claims that the Latins (later known as Roman Catholics) split from the Body of the Church because of Papal claims of supremacy over the Church, and changes to the Nicene Creed (the filioque clause), which were not accepted by anyone else at that time.
There is an Orthodox Church and a Catholic Church. There is no Catholic Orthodox Church.
Eastern Orthodox Church (or the Christian Orthodox Church).
No, the Greek Orthodox church is a part of the Eastern Orthodox Churches.

The Orthodox Church and the Roman Church both have apostolic succession so they are equally old. Anyway at one stage they were one church called the Catholic Orthodox Church or The Universal Truth. The western church (Catholic) wanted to change the creed (a sum of the faith) and started declaring papal supremacy over the other churches - the Orthodox church views the St.Peter on the rock thing a Primacy of Honour not infallibility since Jesus did not make one apostle greater than the other. These were the main events that caused the 1054 schism and creating officially the Catholic and Orthodox Church. However seeing how the Catholic Church changed its teachings,liturgy among other things. The Orthodox Church did not change anything before or after the 1054 schism That is why the Catholic Church views the Orthodox Church as valid, but the Orthodox Church doesn't for the Catholic Church
