The Late Helladic Period (circa 1600-1100 BCE) is a significant phase in ancient Greek history, characterized by the rise of the Mycenaean civilization. This era is marked by the construction of large palatial complexes, advanced pottery styles, and the use of Linear B script, which is an early form of Greek writing. The Mycenaeans engaged in extensive trade and warfare, influencing surrounding regions. During this period, major archaeological sites such as Mycenae, Tiryns, and Pylos flourished. The Late Helladic Period ended with the collapse of Mycenaean society, leading to a transition into the Greek Dark Ages. This decline is attributed to various factors, including invasions and internal strife.
