Bank Zachodni S.A. was a Poland based commercial bank that offered the normal range of retail and commercial banking services created in 1988 from a part of National Bank in South-Western Poland. Allied Irish Banks bought majority of its shares in 1999 and merged it with Wielkopolski Bank Kredytowy in 2001 to form BZ-WBK (which changed its name to Santander Bank Polska in 2018). [1]
