The French conquest of Algeria took place between 1830 and 1847. In 1827, an argument between Hussein Dey, the ruler of the Ottoman Regency of Algiers, and the French consul escalated into a naval blockade following which France invaded and quickly seized Algiers in 1830, and rapidly took control of other coastal communities. Amid internal political strife in France, decisions were repeatedly taken to retain control over the territory, and additional military forces were brought in over the following years to quell resistance in the interior of the country. The methods used to establish French hegemony reached genocidal proportions and war, famine and disease led to the death of between 500,000 and 1 million of an estimated 3 million Algerians.
