Comparative company law starts with the rise of the modern company in the first half of the 19th century. Ever since the need for looking across the border was felt by legislators, lawyers, academics, judges and regulators. Most recently there has been a renewed interest in comparative company law, partly because of the emergence of European company law and partly because the corporate governance movement has sharpened the sense of competition with other countries. Comparative company law follows the close relations of company, capital market and banking law that exist today, in particular after the financial crisis. Comparative company law must also take notice of company self-regulation and the international code movement and is more and more influenced by economic considerations. The chapter concludes with perspectives for future research.
