Applications
Immediately after publishing the Haar theorem, it was used to solve Hilbert's fifth problem which concerns the characterization of Lie groups. Haar measures apply more generally to two fields of mathematics, abstract harmonial analysis and mathematical statistics.
In abstract harmonial analysis, Haar measures are used on locally compact groups, especially with Pontryagin duality.

In statistics, Haar measures are used on prior probabilities for compact groups of transformations. Another area of statistics that Haar measures are used in is conditional inference.
