0:00:07.689,0:00:13.007 History’s first empire rose [br]out of a hot, dry landscape, 0:00:13.007,0:00:18.787 without rainfall to nourish crops, [br]without trees or stones for building. 0:00:18.787,0:00:24.140 In spite of all this, its inhabitants[br]built the world’s first cities, 0:00:24.140,0:00:28.226 with monumental architecture [br]and large populations— 0:00:28.226,0:00:32.542 and they built them [br]entirely out of mud. 0:00:32.542,0:00:36.052 Sumer occupied the southern part [br]of modern Iraq 0:00:36.052,0:00:38.752 in the region called Mesopotamia. 0:00:38.752,0:00:41.932 Mesopotamia means “between two rivers”— 0:00:41.932,0:00:44.892 the Tigris and the Euphrates. 0:00:44.892,0:00:52.033 Around 5000 BCE, early Sumerians used[br]irrigation channels, dams, and reservoirs 0:00:52.033,0:00:58.460 to redirect river water and farm [br]large areas of previously bone-dry land. 0:00:58.460,0:01:02.976 Agricultural communities like this [br]were slowly springing up around the world. 0:01:02.976,0:01:06.766 But Sumerians were the first[br]to take the next step. 0:01:06.766,0:01:09.336 Using clay bricks made from river mud, 0:01:09.336,0:01:13.336 they began to build multi-storied[br]homes and temples. 0:01:13.336,0:01:14.596 They invented the wheel— 0:01:14.596,0:01:19.609 a potter’s wheel, for turning mud [br]into household goods and tools. 0:01:19.609,0:01:23.903 Those clay bricks gave rise [br]to the world’s first cities, 0:01:23.903,0:01:27.693 probably around 4500 BCE. 0:01:27.693,0:01:32.249 At the top of the city’s social ladder[br]were priests and priestesses, 0:01:32.249,0:01:34.382 who were considered nobility, 0:01:34.382,0:01:40.056 then merchants, craftspeople,[br]farmers, and enslaved people. 0:01:40.056,0:01:43.896 The Sumerian empire [br]consisted of distinct city-states 0:01:43.896,0:01:46.506 that operated like small nations. 0:01:46.506,0:01:49.886 They were loosely linked [br]by language and spiritual belief 0:01:49.886,0:01:52.526 but lacked centralized control. 0:01:52.526,0:01:56.881 The earliest cities were Uruk, [br]Ur, and Eridu, 0:01:56.881,0:01:59.721 and eventually there were a dozen cities. 0:01:59.721,0:02:04.636 Each had a king who served a role [br]somewhere between a priest and a ruler. 0:02:04.636,0:02:09.033 Sometimes they fought against [br]each other to conquer new territories. 0:02:09.033,0:02:14.736 Each city was dedicated to a patron deity,[br]considered the city’s founder. 0:02:14.736,0:02:19.898 The largest and most important building [br]in the city was this patron god’s home: 0:02:19.898,0:02:24.485 the ziggurat, a temple designed[br]as a stepped pyramid. 0:02:24.485,0:02:30.029 Around 3200 BCE, Sumerians began [br]to expand their reach. 0:02:30.029,0:02:34.295 The potter’s wheel found a new home [br]on chariots and wagons. 0:02:34.295,0:02:37.785 They built boats out of reeds [br]and date palm leaves, 0:02:37.785,0:02:42.984 with linen sails that carried [br]them vast distances by river and sea. 0:02:42.984,0:02:46.542 To supplement scarce resources, [br]they built a trade network 0:02:46.542,0:02:51.180 with the rising kingdoms in Egypt, [br]Anatolia, and Ethiopia, 0:02:51.180,0:02:57.785 importing gold, silver, [br]lapis lazuli, and cedar wood. 0:02:57.785,0:03:00.235 Trade was the unlikely impetus 0:03:00.235,0:03:03.985 for the invention [br]of the world’s first writing system. 0:03:03.985,0:03:07.185 It started as a system of accounting[br]for Sumerian merchants 0:03:07.185,0:03:09.885 conducting business with traders abroad. 0:03:09.885,0:03:13.735 After a few hundred years, [br]the early pictogram system 0:03:13.735,0:03:17.085 called cuneiform turned into a script. 0:03:17.085,0:03:20.025 The Sumerians drafted up the first[br]written laws 0:03:20.025,0:03:24.814 and created the first school system, [br]designed to teach the craft of writing— 0:03:24.814,0:03:31.317 and pioneered some less exciting[br]innovations, like bureaucracy and taxes. 0:03:31.317,0:03:34.837 In the schools, scribes studying [br]from dawn to dusk, 0:03:34.837,0:03:37.627 from childhood well into adulthood. 0:03:37.627,0:03:42.004 They learned accounting, mathematics,[br]and copied works of literature— 0:03:42.004,0:03:47.415 hymns, myths, proverbs, animal fables, [br]magic spells, 0:03:47.415,0:03:50.845 and the first epics on clay tablets. 0:03:50.845,0:03:54.145 Some of those tablets told [br]the story of Gilgamesh, 0:03:54.145,0:03:59.770 a king of the city of Uruk who was[br]also the subject of mythical tales. 0:03:59.770,0:04:05.887 But by the third millennium BCE, Sumer[br]was no longer the only empire around, 0:04:05.887,0:04:08.117 or even in Mesopotamia. 0:04:08.117,0:04:13.661 Waves of nomadic tribes poured[br]into the region from the north and east. 0:04:13.661,0:04:17.661 Some newcomers looked up to the Sumerians,[br]adopting their way of life 0:04:17.661,0:04:21.661 and using the cuneiform script [br]to express their own languages. 0:04:21.661,0:04:29.026 In 2300 BCE, the Akkadian king Sargon[br]conquered the Sumerian city-states. 0:04:29.026,0:04:31.696 But Sargon respected Sumerian culture, 0:04:31.696,0:04:37.262 and Akkadians and Sumerians[br]existed side-by-side for centuries. 0:04:37.262,0:04:41.382 Other invading groups focused [br]only on looting and destruction. 0:04:41.382,0:04:43.842 Even as Sumerian culture spread, 0:04:43.842,0:04:51.738 a steady onslaught of invasions killed[br]off the Sumerian people by 1750 BCE. 0:04:51.738,0:04:55.944 Afterward, Sumer disappeared [br]back into the desert dirt, 0:04:55.944,0:05:00.037 not to be rediscovered[br]until the 19th century. 0:05:00.037,0:05:04.037 But Sumerian culture lived [br]on for thousands of years— 0:05:04.037,0:05:09.155 first through the Akkadians,[br]then the Assyrians, then the Babylonians. 0:05:09.155,0:05:13.045 The Babylonians passed Sumerian [br]inventions and traditions through 0:05:13.045,0:05:16.798 along Hebrew, Greek, and Roman cultures. 0:05:16.798,0:05:19.208 Some persist today.
