The "Common Era" begins in the year 1 AD, and continues to the present day. 2011 is the Two thousand and eleventh year of the Common Era. The period before 1 AD is known as "Before Common Era", and it extends from 1 BC backward in time to the beginning of human history.

If by "Common Era" you are referring to the era name system, then Christianity coincided with the beginning of the Common Era. In fact, the Common Era is also known as the "Christian Era" or "Current Era". The year 1 CE is the year in which a 6th century monk estimated that Jesus had been born when he created the Common Era calendar.
Common Era or Current Era, abbreviated CE, is a calendar era that is often used as an alternative naming of the Anno Domini era ("in the year of the Lord"), abbreviated AD. The system uses BCE as an abbreviation for "before the Common (or Current) Era" and CE as an abbreviation for "Common Era". As of 2016, it started 2016 years ago.
C.E. means common era which pertains to the exact time period as A.D. or Anno Domini. B.C.E refers to before common era which is like B.C.

The term "Common Era" refers to the period after the birth of Jesus. That occurred while the Roman Empire ruled a large part of Europe and the Mediterranean area. Michelangelo was born in 1475 CE, that is, 1475 years after the birth of Jesus, during the period of time known as the Renaissance.
BCE is the acronym of "Before the Common Era" in indicating dates. This is becoming the common indicator in place of the old BC or "Before Christ" used to indicate dates more than 2020 years ago. Most of the world does not use the birth of the Christian's Jesus as an important date and the change makes the use of a common dating system more palatable.
