History of Latvia between 2000 BC - 1 BC
In about 2000 BC a new wave of colonists flowed into the Baltic area from the South. They settled down in East Prussia, Lithuania and Southern Latvia. This invasion continued in the Bronze Age (1500—500 BC) and the older Iron Age (500—0 BC). During these periods two cultural routes are playing a great part in the development of Baltic culture. One of these leads over East Prussia to Central Europe, the other across the sea to Scandinavia.
Some forms of graves, tools, arms, and burial customs lead one to suppose that the continuous development of these prehistoric cultural forms of the Baltic is sufficient to prove that the bearers of this civilization were the forefathers of the present Baltic nations. Thus, the ethnic history of these people can be traced back to about 2000 BC.
At the beginning of our era the common original Baltic culture had already branched into the Western (later Borussian or Ancient Prussian) and Eastern (later Lithuanian and Latvian) cultures. Even in that age, as is shown by archaeology and linguistics, the relations in culture and trade between the Balts and the Finno-Ugrians were considerable and close. At any rate, this development took place some time before the Teutons established direct contact with both races.
The Bronze Age (1500–500 BC) witnessed the transition from an economy based on food procurement to one based on food production. Stock-keeping and agriculture became increasingly important. In the Older Iron Age (500 BC - 0 AD), the first iron objects came into use.

Previous historical period: Neolithic Age (-3000--2001) | Next historical period: Roman Iron Age (0-399)The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
