In East Sumatra, in the beginning of 20th century Islamic School (madrasah) is established. The
islamic is established both by sultan and society. In 1912 Sultan Abdul Aziz Abdul Jalil Rahmatsyah finds an
organization called Jam'iyah Maḥmudiyah li Ṭalabil Khairiyah. In that year also the board establishes Islamic
school on level of kindergarten (tajhiziyah) ,primary school (ibtidaiyah), junior high school (ṡanawiyah), and
senior high school (al-qismul 'ali) in Tanjung Pura. In 1918, the Mandailing community in Medan establishes an
Islamic school (madrasah) named Maktab Islamiyah Tapanuli where this education also manages kindergarten
(tajhiziyah) until senior high school (al-qismul 'ali). The Moslem in Medan in 1930 finds an organization called
Al Jam'iyatul Washliyah, and in 1935 the Al Ittihadiyah organization is established. Organizations founded by
Moslems in Medan in the beginning of the 20th century also establishe Islamic school (madrasah). The Al
Jam'iyatul Washliyah organization begins opening the Islamic school in 1932. Al Ittihadiyah begins to open the
Islamic school in 1935.
Meanwhile Sultan Sulaiman Syariful Alamsyah who rules in Serdang Sultanate also finds a school
named Sairus Sulaiman. In Tanjung Balai in the beginning of the 20th century there is also an Islamic school
established by H.M. Isa, Arabiyah Islamic school while Sheikh Ismail bin Abdul Wahab finds the Islamic school
of Gubahan Islam. Regarding education in the Japanese era called "Hakko Ichiu", invites the Indonesian people
to work together to achieve prosperity with Asia Raya. The schools that exists in the Dutch period are replaced
by the Japanese system. Therefore the students every day especially in the morning must always swear
allegiance to the Emperor of Japan, and they are trained military. The school system of the Japanese era is quite
different of the Dutch. There is a fundamental change in the field of education for the Indonesian nation at the
time, which is the elimination of the dualism of teaching and use of Indonesian language. Nevertheless, the
attitude of the Japanese colonist to Islamic education is softer, so the space for Islamic education is more free.
Japan is not so concerned about religious interests, what is important to them is how to win the war. Japan even
gives freedom for religious leaders to develop their education. At the time of the Japanese occupation there is a
privilege in the field of education found by the Indonesian nation, ie schools have been uniformed and legal.
Although private schools like Muhammadiyah, Taman Siswa and other schools are allowed to continue to be
developed with the regulation and implementation undertaken by the Japanese. Islamic school is built
countinually, this case can be seen in Sumatra that is famous for Madrasah Awaliyah inspired by Majelis Islam
