What is the World Law Timeline?
The World Law Timeline lays out every law in the library chronologically by the decade it was enacted, from oldest to most recent, so you can see how legislation in a country or category evolved over time instead of browsing laws as a flat, unordered list.
Filter the timeline down to a specific country or legal category to focus on how that country's, or that category's, laws have built up decade by decade — useful for spotting legislative trends, like when a wave of a certain type of law was enacted across a region.

Can I filter by legal category?
