The bronze age

Explains what the term Bronze Age refers to, when it occurred, and what its significance is to the development of civilization

The Bronze Age refers to a period of time in earth’s history, beginning approximately 3800BC – 3000BC, during which certain cultural developments occurred. Preceded by the Paleolithic, Mesolithic, and Neolithic (New Stone Age) periods and followed by the Iron Age, the Bronze Age is noted as an era when copper and bronze, which is an alloy derived from copper and tin, was used extensively to make tools, weapons, and other decorative items. Additionally, because of the rapid use of the tools made during this time period, commerce and trade grew tremendously.

This is because workers were needed to remove the precious ore, tradesmen were needed to smelt the materials mined, craftsmen were needed to develop molds for the smelted ore, and artisans were needed to finalize the tools and decorative goods produced. Another influential development that occurred to civilization during this time was the invention of the horse-drawn, two-wheeled chariot. Aided by the advancement in more sophisticated tooling techniques, the introduction of this type of chariot helped to advance military strategies. This is because the new chariot was an extremely mobile, yet strong, wagon that could out maneuver the previous carts used in warfare up until this time.

In regard to the actual term, “Bronze Age”, it was coined by Christian Thomsen in 1816. Thomsen was a Danish museum curator who used this term as part of a museum classification scheme to describe items excavated from the earth during a certain era. Later on, however, scientists, specifically geologists, decided to use Thompson’s term to categorize rock layers that developed during different geological time frames. Once in use by scientists, the general public came to accept, and to use, the term as well.

Although the Bronze Age can be traced to many different parts of the world, including throughout the ancient civilizations of Mesopotamia, Sumer, Indus, China, the Aegean (the Minoans and Mycenaeans) and Britain, it did not reach the cultures of ancient Africa, nor did it obtain great heights in the pre-Columbian civilizations within the Americas (the Aztecs and Incas). However, where it did influence tooling technologies it was usually preceded by a period where crafting with copper was used first. The exception to this was in China and Britain where the transition from the New Stone Age to Bronze Age did not include a copper stage. This was indicated by the lack of copper items in these areas and the direct replacement of existing stone-made tools and decorative items by their bronze tooled counterparts.

As early as 3800BC, bronze was being used to make tools and implements. This was discovered in Iran where archaeologists found items that indicated a mix of copper and other metals were being combined to produce a bronze substance. However, this ancient production was more likely accidental than predetermined, with the result both surprising and pleasing its ancient producer. For, after that initial accident, early civilizations began to experiment with smelting processes in order to produce a purer bronze. It was at this point in time that the Bronze Age entered a new phase.

While copper and bronze items were used concurrently during the Bronze Age, once people learned how to produce bronze properly, the reason that they worked with it more extensively, or made a direct transition to using bronze solely, was because bronze was more durable than copper and could be reworked simply should a bronze piece become damaged or destroyed. Bronze tools including knives, axes, and other cutting instruments could also be sharpened more easily than those made from copper, thus reducing the time required for workers to perform their jobs. Because workers had better tools and could work faster, the creation of larger building structures and the development of urban areas also grew during this time period. Having tools that could expedite a work process encouraged people to build more and thus, civilization flourished during this era.

During the Bronze Age many artists were encouraged to produce works that were both functional as well as artistic. Because of this, owning elaborate bronze decorative items helped to establish status during this time period. For example, many members of the upper class of Mesopotamia were often buried with their personal bronze crafted items. Meanwhile, in Europe, the hand works of the Uneticians were prevalent. These people comprised a farming and metalworking community in what is now the Czech Republic. They were skilled crafts people who helped spread the advancement of art, culture, and metal works into the Central European region.

The end of the Bronze Age occurred with the advent of another metal, iron. Introduced in the ancient Near East, iron quickly became a popular replacement for bronze. And, once iron was used, it became the primary metal of choice for the creation of tools, weapons, and other household items. Thus, the Bronze Age dissipated, as had other previous eras, with civilization moving on to use newer and more advanced technologies.

Alexander the Great - biography

Alexander the Great, who would become the Conqueror of the Ancient World, was born at Pella, Macedonia in 356 B.C.E. His father was King Phillip II and his mother was Olympias, a deeply spiritual woman who taught her son that he was a descendant of Achilles and Hercules. From the earliest age, then, Alexander was conditioned for conquest and kingly glory. He, thus, became focused on being a great ruler.

When he was 13, Alexander became student to the great Greek philosopher Aristotle. Under Aristotle’s tutorship he gained an interest in philosophy, medicine and science. However, Aristotle’s concept of small city-state government would not have gone down well with the young prince who was bent on world domination. Aristotle did, however, cultivate Alexander’s interest in reading and learning.

At age 16 Alexander was called to Macedonia to put down a Thracian rebellion while his father was away. Distinguishing himself immediately, Alexander quelled the rebellion, stormed the rebel’s stronghold and renamed it Alexandroupolis, after himself.

In 336 B.C.E. Phillip was assassinated and 20 year old Alexander took the throne of Macedonia. Within two years he had embarked on his campaign of conquest. His army of 30,000 foot soldiers and 5,000 cavalreymen was small but efficient. Along with the army he took engineers, surveyors, architects, scientists and even historians.

The first engagement was against the Persians at the Granicus River in modern day Turkey. Defeating the Persians he swept through western Asia Minor. The next Autumn the second major encounter against the Persians took place at Issus, in the south eastern corner of Asia Minor. Persian king Darius III had amassed an army of about half a million to wipe out the Greek threat. But the vicious and tactically superb attack mounted by Alexander routed the Persians, despite being outnumbered about 13 to 1.

Alexander now turned south, marching along the Mediterranean coast His only resistance came from the island city of Tyre. Alexander began a siege that would last for seven months. Finally Tyre was completely destroyed in July, 332 B.C.E.

Alexander now pushed further south, conquering Gaza and then moving into Egypt where the people welcomed him as a deliverer from their Persian rulers. Now Alexander turned north east, moving through Palestine towards the Tigris River. In 331 B.C.E. he met the Persians for the third time. The Battle of Gaugamela saw him defeat superior odds once more. Persian King Darius was later killed by his own people. Swiftly Alexander pushed through to take the Persian Capital at Babylon. He humiliated the Persians by burning their great palace at Xerxes. Before long the entire Persian domain was under Alexander’s control. He now crossed the Indus River and entered the region bordering the Persian province of Taxila. Here he met the feared Indian Monarch Porus who, with 25,000 men and 200 elephants nearly did what the entire Persian Kingdom could not. After fierce fighting, however, Alexander was once more victorious. Porus surrendered and became an ally.

After an eight year campaign Alexander was now ruler of a massive empire. He was keen to push further west but his men were weary and intent on returning to their families. Reluctantly he complied with their wishes.

Alexander was a caring military leader. He would visit his men after the battle, examining their wounds and praising them for their valiant efforts. He would also arrange extravagant funerals for the fallen. He would arrange games and contests for his men. The affection for their leader was what galvanized his troops.

Returning to Babylon Alexander assumed the role he had coveted for so long – The great Conqeuror. Eventually, however, he gave way to a licentious lifestyle of excessive drinking. He also gave way to fits of rage and paranoid suspicion. One night he even murdered his closest associate, Clitus, in a fit of rage. This act was to haunt for the remainder of his short life.

In June, 332 B.C.E Alexander fell victim to malarial fever. He never recovered. The man who no man could defeat died on June 13, 323 B.C.E. He was just 32 years and 8 months old.
