dates before1189AD the beginning of the reign of richard 1 were defined in english law by what two word term?

Answer 1

TIME IMMEMORIAL. The use of this expression to mean "a time before legal history, and beyond legal memory." was established by statute in 1276, as the year 1189, the beginning of the reign of King Richard I. "Proof of unbroken possession or use of any right since that date made it unnecessary to establish the original grant."

But note that in 1832 the used of a fixed date ended.
"Instead, it was held that rights which had been enjoyed for twenty years (or as against the crown thirty years) should not be impeached merely by proving that they had not been enjoyed before."
Webster's Revised Unabridged Dictionary (1913)

Also explained in the "Dictionary of Cliches" by James Rogers (Ballantine Books, New York, 1985).

Answer 2

I think you might mean the Dark Ages. This is defined as a time of intellectual darkness in Europe from around the 5th to 12th century.

However, there's also the Middle Ages, the time between the fall of the Roman empire and the Renaissance - 5th to 15th century. Hope this helps.

Answer 3

Time immemorial, 189 year's after my ancestor's landed on the shore's of Ireland, those bloody Viking's get everywhere.

Answer 4

"Time immemorial". is the legal term for the distant past beyond legal memory. This was declared by statute (but I can't quote the name of the Act concerned).
