The development of Muhammadiyah in West Java has been so far considered lagging behind, even though historical records show that the development of Muhammadiyah in West Java, especially in Garut in 1923, was included in the early period of its establishment.

They built educational charities and developed other branches in Priangan (Tasikmalaya, Kuningan, Bandung and Sukabumi) as well as West Java. The merchants at that time were an elite group who had respectable social positions, so they could establish good relations with many parties for business, political and da'wah interests. Through this social role, batik merchants in Garut easily communicated with priyayi groups, religious leaders, and political figures at that time.
