The Playstation War
Playstation 2
The PlayStation 2, commonly known as the PS2, would go on to become
the best-selling videogame console of all-time, selling some 150 million
units.
[22] 
Upon
its release in 2000, Playstation fever stretched from Japan to the
US. The console sold nearly one million units—the entire available
supply– on the first day of sales, with millions more consumers waiting
for theirs on backorder.
Tantalum Price Surge
The late 1990’s and 2000 also saw a continued upswing in cell-phone
sales, combined with a surging dot-com market. The convergence of
technological demand would have a profound effect on the materials mined
in the DRC.
Tantalum—mined as coltan and an integral part of cell phones and
Playstations–found itself in short demand, and the price skyrocketed
ten-fold overnight. The “coltan rush” in DRC lead to a vicious fight
for control over the mines, and the “black gold” they held. Farmers
near coltan regions were forcibly driven from their lands, villages were
brutally attacked, women raped, and thousands displaced.

Those not forced to mine by the militia were expected to handover part or all of their payload coltan as a form of payment.
[23]
In addition to the human toll, militias eager to exploit the mines
ravished the natural landscape and forests. Endangered gorillas were
either killed, or driven from their habitat, as Congo’s national
parks—prime coltan mining ground—were quickly overrun.
[24]
A U.N. Security Council detailed the effects of the price surge:
“In 1999 and 2000 a sharp increase in the world prices of
tantalum occurred, leading to a large increase in coltan production in
eastern Democratic Republic of the Congo. Part of that new production
involved rebel groups and unscrupulous business people forcing farmers
and their families to leave their agricultural land, or chasing people
off land where coltan was found and forcing them to work in artisanal
mines. As a result, the widespread destruction of agriculture and
devastating social effects occurred, which in a number of instances were
akin to slavery.” [25]
Prior to the price-spike, coltan prices captured a market price of $80 to $100 a pound. By December the price had reached $380.
[26]
With the surge in tantalum prices, Rwandian, Ugandian and indigenous
Congolese militias rushed to grab as much coltan as they could, with
proceeds financing their military efforts. It’s estimated that as much
as $20 million a month went to rebel groups to finance war efforts.
[27]

Both
the forced production of coltan, and the military power created through
its production, would wreak havoc on the Congolese people.
“This
historical event—the moment of the price hike—was also a time when
violence came to be directed at everyday social production, as women
were raped and “cursed” from marrying and bearing children, crops and
livestock were stolen, and ordinary people were forced into slave labor
for militias.” [28]
