What is the meaning of c2000-1100BCE?

Answer 1

BCE means 'before the common era', and is an attempt to refer to the commonly accepted numbering of years but without the religious implication. CE means 'common era'. So AD (Anno Domini, or year of our Lord) and CE (common era) refer to exactly the same range of years. BC (Before Christ) and BCE (before common era) do the same thing. The 'c' before 2000 may refer to 'circa', meaning roughly, about, or around. So the reference could be to the time period between C.2000 and 1100 BCE. The larger number refers to the earlier year BCE.
