The two World Wars curbed the continuous expansion that Wallonia had enjoyed up till that time. Towards the end of the 1950s, things began to change dramatically. The factories of Wallonia were by then antiquated, the coal was running out and the cost of extracting coal was constantly rising. It was the end of an era, and Wallonia has been making efforts to redefine itself. The restoration of economical development is high on the political agenda, and the government is encouraging development of industries, notably in cutting edge technology and in business parks. The economy is improving, but Wallonia is not yet at the level of Flanders and is still suffering from difficulties.
