Why the Late Bronze Age world of the Eastern Mediterranean collapsed

The decline of the Indus-Saraswati civilization was not caused by invading or migrating Aryans, instead the fate of the cities was affected by tectonic movements and hydrological changes. From the late 1950s, historians believed that Mohenjo-daro was destroyed due to tectonic shifts in the region. According to one version, tectonic movements blocked the course of lower Indus river which must have caused floods that submerged the city. An opposing and the currently favoured theory suggests that instead of submerging in water, the city was starved of water. This happened because Indus shifted away from Mohenjo-daro, thus disrupting the crop cycle as well as the river-based communication network.

For the Saraswati, there are multiple theories. While one study claims that Ghaggar was a monsoon fed river and hence was easily susceptible to the vagaries of declining rainfall, there is another which shows that Sarasvati was a glacier-fed river and climate is not the only cause for changes. I discuss the details in my post What caused the decline of Harappa?

Eight centuries after the events in North-West India, the complex civilizations around the Mediterranean which comprised of thee Aegeans, Hittites, Egyptians and Syro-Palestinians collapsed and disappeared from history. This decline, in a similar manner to the collapse of the Indus-Saraswati civilization was blamed on invasion.  It was assumed that Sea People invaded at the Nile delta, Turkish coast, and even into Syria and Palestine. New evidence indicates that there was a climate-change driven famine and the association with the sea people is causal.

By combining data from coastal Cyprus and coastal Syria, this study shows that the LBA crisis coincided with the onset of a ca. 300-year drought event 3200 years ago. This climate shift caused crop failures, dearth and famine, which precipitated or hastened socio-economic crises and forced regional human migrations at the end of the LBA in the Eastern Mediterranean and southwest Asia. The integration of environmental and archaeological data along the Cypriot and Syrian coasts offers a first comprehensive insight into how and why things may have happened during this chaotic period. The 3.2 ka BP event underlines the agro-productive sensitivity of ancient Mediterranean societies to climate and demystifies the crisis at the Late Bronze Age-Iron Age transition.[Environmental Roots of the Late Bronze Age Crisis]

Pirates of the Mediterranean

Since Indian Navy is hunting pirates near Somalia, this would be a good time to listen to a pirate story.
Sometime in 75 B.C.E, Cilician pirates in the Mediterranean sea captured a young Roman orator. The pirates asked for a ransom of twenty talents to which the Roman laughed. He said he was worth a lot more and promised fifty. While his followers went to collect money, the Roman spent thirty eight days as a hostage.
During that time he acted as if he was the master. When he wanted to sleep, he ordered the pirates to be quiet. He played any sport he liked, wrote poetry and made speeches, while the pirates silently suffered. When the pirates showed no appreciation of his talent, he called them illiterate savages. He also jokingly said that he would hang all of them at the opportune moment.
The ransom soon arrived, much to the delight of the pirates, and the hostage was set free. The Roman followed the pirates, captured them, and put them in prison. When he asked the governor of the land to punish the pirates, the governor seemed not to be interested. The Roman then took matters into his hands, went to the prison, and hung all the pirates on a cross as he had promised.
This is why in Tortuga, when a pirate baby cries, the mother says,  beta, so jaa, nahi toh Julius Caesar aa jaayega. (via)
