Step 1: Set the scene.
By the 1830s, Europe's population had grown quickly, but jobs and food supply had not kept pace, so ordinary families felt the squeeze from more than one direction at once.
Step 2: Look at the job market.
Factories and machine made goods undercut traditional artisans and craftsmen, leaving many skilled workers without steady work, while a growing labour force kept wages low.
Step 3: Look at food and prices.
Poor harvests reduced the food supply just as more mouths needed feeding, so prices for bread and other basics rose sharply and hit the poor hardest.
Step 4: Connect this to later unrest.
This mix of unemployment, high prices and falling living standards built up frustration that fed directly into the liberal and nationalist uprisings of the following years, so the 1830s truly were a decade of economic hardship in Europe.
