Incorporation
Since 1865 state banks and trust companies have been incorporated by the use of one of three methods: (1) By special charter; (2) under the "business incorporation law"; (3) under the general banking law. Not very many of the States have used consecutively all three methods, for the special charter and the "business incorporation law" were used contemporaneously in different sections of the country. Both have given place, in the great mass of States, to the general banking law. From 1865 to 1875 probably the greater number of the banks formed were incorporated under special acts; from 1875 to 1887 incorporation under the "business incorporation law" was the prevailing method, and since then the general banking law has become the almost universal method of incorporating banks and trust companies.
