Tribalism is one of the major defects of democracy in nigeria today. Nigeria is made up of three major ethnic group(yoruba,igbo and hausa) and these three groups have not been in goods terms since the creation of the country. A yoruba man for example wouldn't patronise an igbo man in the buying of his goods because he feels he would be cheated and deceived by the later. while an igbo man would have nothing to do with an hausa man because he sees them as devils and the pain of the civil wars are still fresh in his memories.so in order to advoid getting in trouble with themselves, every man runs business with his tribe. If tribalism continues in nigeria, our country would not progress and there would be continues crises and problems among the three ethnics groups in nigeria
