What are the facts concerning resurrection of Jesus Christ according to general documents like the Bible, contemporary historians etc? I mean by facts, statements that authors wrote that are actual historical events.
Hands down, Eusebius is your best bet for an "historical" (by which I assume you mean non-biblical) account of the early church.
Eusebius is often called the 'Father of Church History'. Although he was not active until the 200s, his work is usually considered by historians of all types - from Dan Wallace to Bart Ehrmann to be the pre-eminent collector of "facts" closest to the source. His work Church History has been available since then, and is often the source text for modern histories, such as those by McDowell, Stroebel, and thousands of others.
The two most well-known extra-biblical sources about the life of Jesus Christ come from two contemporary "historians"
Neither of these two are completely disinterested parties - each has agendas of their own. Josephus, having not died at Masada, had his own reputation to save. Tacitus, as a good Roman senator, couldn't come out and associate himself with the lowest classes - the Christians.
As such, the best contemporary documents about the life of Jesus are probably by those who knew him best:
- Matthew, a tax Collector who travelled with Jesus
- Mark, a friend of Jesus' closest disciple (Peter)
- Luke, a doctor who travelled with Paul who wrote two books - a Gospel and an early history of the church called 'Acts'
- John, a disciple of Jesus.
