was held in
Zurich in August 1897.
On its 40th anniversary in 1938 the society was renamed the Bulgarian Physical and Mathematical Society, due to its increasing national importance in Bulgaria.
It stopped functioning in 1950 and was re-established in 1960.
On 17 October 1971 the society amicably split into the Society of Bulgarian Mathematicians and the Society of Bulgarian Physicists (now the Union of Physicists in Bulgaria).
The first president of the independent mathematical society was Alipi Mateev.
In April 1977 the society changed its name to the Union of Bulgarian Mathematicians.
Activities and publications
Since 1968 the Union of Bulgarian Mathematicians holds an annual spring conference with a scientific programme.
Reports from the spring conference are published in the society journal ''Mathematics and Education in Mathematics'', which was founded in 1972.
The UBM organises several conferences and seminars at a national level, and is involved in the running of mathematics competitions for students, as well as in sending a team to the International Olympiads in
