One of his most important works was 'History of Peloponnesian War', in which he described an ancient Greek war between Athens and its empire and the Peloponnesian League led by Sparta in 5th cntury BC. Thucydides is considered to be the father of 'scientific history' because of his strict standards of evidence-gathering and analysis of cause and effect without reference to intervention by the gods.
