This region, situated between the Tigris and Euphrates rivers, provided fertile land that supported agriculture and enabled the growth of complex societies. Key city-states included Ur, Uruk, and Lagash, each functioning as independent political entities with their own governance and culture.

Sumer was an ancient civilization located in the southern part of Mesopotamia, primarily in what is now modern-day Iraq. It is considered one of the world's earliest urban cultures, flourishing around 4500 to 1900 BCE. Sumerians are known for their innovations in writing (cuneiform), governance, and architecture, as well as significant contributions to mathematics and astronomy. The civilization is characterized by city-states such as Ur, Uruk, and Eridu, each with its own ruler and deity.

The Sumerians are credited with many pioneering achievements, but one of their first significant accomplishments was the development of cuneiform writing around 3200 BCE. This early form of writing allowed them to record transactions, laws, and stories, marking a major advancement in communication and administration. Additionally, they established urban centers, complex irrigation systems, and engaged in trade, laying the foundation for future civilizations.

Egypt and Sumer were considered civilizations because they developed complex societies characterized by urbanization, social stratification, and centralized governance. Both regions had advanced agricultural practices that supported large populations, alongside innovations such as writing systems (hieroglyphics in Egypt and cuneiform in Sumer) that facilitated record-keeping and communication. Additionally, they made significant advancements in technology, architecture, and trade, contributing to their status as foundational cultures in human history. Their rich cultural and religious practices further distinguished them as civilizations.

The life span of a Sumerian during ancient times typically ranged from 30 to 40 years, although some individuals might have lived longer, particularly those with better access to resources and healthcare. Factors such as disease, malnutrition, and warfare significantly impacted mortality rates. Archaeological evidence suggests that infant mortality was high, which contributed to the overall lower average life expectancy.

The physical environment of Mesopotamia, particularly the fertile land between the Tigris and Euphrates rivers, was crucial for the development of Sumerian civilization. The rich alluvial soil enabled the cultivation of crops, which supported agricultural surpluses and led to population growth. Additionally, the rivers provided essential water resources for irrigation, facilitating the transition from nomadic lifestyles to settled farming communities. This agricultural foundation allowed for the rise of complex societies, trade, and the emergence of city-states in Sumer.

The Sumerians used a base-60 (sexagesimal) numbering system, so the number 65 would be represented as 1 unit of 60 and 5 units of 1. In their cuneiform script, this would be depicted as a symbol for 1 followed by the symbol for 60, and then a symbol for 5. The representation would vary based on the context, but it would essentially convey the concept of 1 group of 60 plus 5.

In Sumerian society, priests held significant power due to their role as intermediaries between the gods and the people. They were responsible for performing rituals, maintaining temples, and ensuring the favor of the deities, which was crucial for agricultural prosperity and societal stability. Their control over religious practices also granted them substantial economic influence, as temples often managed vast resources and land. This combination of spiritual authority and economic power positioned priests as key figures in Sumerian governance and daily life.

The Sumerians developed cuneiform writing, one of the earliest systems of writing in history. This script was created by pressing a stylus into soft clay tablets, forming wedge-shaped marks. Cuneiform was used for various purposes, including record-keeping, legal documents, and literature, allowing the Sumerians to document their culture and communicate complex ideas. It laid the foundation for subsequent writing systems in the region.

A band-organized society is a type of social organization typically characterized by small, mobile groups of people who rely on hunting, gathering, and foraging for subsistence. These societies are often egalitarian, with minimal social stratification and leadership roles that are informal and based on skills or consensus rather than formal authority. Band-organized societies emphasize cooperation, sharing, and communal living, often fostering strong social bonds among members. Examples include various Indigenous groups and nomadic tribes.

Chestnut Husband was a key figure during the events at Fort Sumter, serving as a Union officer in the early stages of the Civil War. His involvement included coordinating supply efforts and maintaining morale among the troops stationed at the fort. Despite facing overwhelming odds, his leadership contributed to the Union's defense efforts, highlighting the challenges faced by military leaders during the conflict. Overall, his role underscored the complexities of the situation at Fort Sumter as tensions escalated into war.

In ancient Sumer, society was divided into four main classes: the ruling class, which included kings and priests; the upper class of wealthy merchants and landowners; the lower class of farmers and artisans; and the enslaved people who were often captured in warfare or born into servitude. The ruling class held significant power and influence, while the upper class contributed to the economy through trade. The lower class formed the backbone of agricultural production, and enslaved individuals had limited rights and were primarily forced to work for their masters. This hierarchical structure played a crucial role in the functioning of Sumerian civilization.

The Sumerians used the wheel primarily for transportation and pottery. In transportation, they created wheeled vehicles such as carts and chariots, which facilitated trade and movement of goods across their city-states. For pottery, the potter's wheel allowed for more efficient and uniform production of ceramic items. This innovation significantly impacted their economy and daily life, enhancing trade and craftsmanship.

The city of Sumer faced several weakening forces, including environmental challenges such as droughts and salinization of soil, which diminished agricultural productivity.
