The First Council of Nicaea convened in A.D. 325, it settled the Christological issue of the relationship of Jesus to God the Father, constructed the first part of the nicene Creed, settled the calculation of the date of Easter (removing it from any reference to the Jewish calendar), and promulgation of the first code of canon law.

It was written at the council of Nicaea (A.D. 325) and modified at the council of Constantinople (A.D. 381)
Although it was not finalised until many years later, the Nicene Creed was formulated by the Council of Nicaea in the year 325, and is the result of that Council.
The two councils are the council of Nicaea and the council of Constantinople.
The Nicene Creed, also known as the Credo, was written in the 4th century, specifically during the First Council of Nicaea in 325 AD.
The Nicene Creed was adopted in the city of Nicaea by the First Ecumenical Council, which met there in the year 325.
During the Council of Nicaea AD 325.
The Nicene Creed was accepted by the Council of Trent because it is one of the foundational statements of Christian belief, affirming key doctrines such as the Trinity and the divinity of Christ. The Council of Trent sought to uphold traditional Christian teachings, and the Nicene Creed was seen as a unifying statement of faith that transcended denominational differences.
Roman Catholic AnswerThe original Nicene Creed came out of the Council of Nicaea in 325 A.D., it was much shorter than the Creed that we use now and call by the same name. That Creed ends with the phrase "and in the Holy Spirit", after that were attached four anathemas against Arianism. The Nicene Creed that we recite at Mass each week is an amplified Creed which was written by the Council of Constantinople in 381 A.D..
The bishop representing Rome at the First Council of Nicaea in 325 AD was Pope Sylvester I. Although he did not attend the council in person, his authority and leadership were significant in shaping the proceedings and outcomes of the council, particularly concerning the Arian controversy and the formulation of the Nicene Creed.
At the Council of Nicaea in 325 AD, the Nicene Creed was established as a statement of faith that defined the beliefs of the Christian church, particularly in affirming the divinity of Jesus Christ.
For Christian update: There is more then 1 Nicene Creed. The original was lost but remorm;ulated at the 2nd ecumenicl council of Constantinople in 381. Difference between the original Creed and the one of today is that it contains addition language reinforcing Catholic and Protestant affirmation. There has been no update since then
AnswerThe Roman emperor Constantine did not personally develop the Nicene Creed, but he did call the Council of Nicaea and lend it imperial authority in its deliberations. The bishops present at the Council decided matters of theology, but looked to Constantine for leadership.
