This article has been prepared for a meeting of the German Vereinigung für Rechtssoziologie on „The Society of Economy“, which took place in Siegen, April 7-9, 2005. The article tries to give an overview on how legal sociology has dealt with the relationship of law and economy. Its intention is not to serve as an introduction to the papers which have been presented at the meeting and are selected for publication in this volume. The overview starts with a short referral to the work of Max Weber and Niklas Luhmann. Than it touches five topics: Economic Analysis of Law, History of Law and History of the Economy, Law as Infrastructure, and finally Globalization of the Economy and Law's Cultural Lag.
