Black History Month is also known as the African-American History Month. It is celebrated all over the United States of America and Canada in the month of February, while in the United Kingdom it is celebrated in October. Each and every school and university conducts various activities to make the generation aware of the importance that African-American history holds in the nation. The electronic media is filled with themes in relevance to the occasion, and many activities are carried out across the country to remember the contribution made by African-American citizens in the development of this nation.

Black History Month was first started by a famous African-American historian Dr. Carter G. Woodson in the year 1926. February was chosen as the month to celebrate the African-American history because it was the birth month of two of the most highly valued people among African-Americans. These were President Abraham Lincoln, who freed the slaves, and Frederick Douglass, who was also the first vice presidential nominee (被任命者) among African-Americans. Initially, Black History Month was known as the “Negro History Week”. This was Dr. Woodson’s attempt to encourage awareness among citizens about the contribution of African-Americans towards the building of the nation. It was only in the early 1970’s that the name “Negro History Week” changed to “Black History Month”. And later, in the year 1976, the entire month of February was declared to be the National African-American History Month, or the Black History Month.

Every year, National African-American History Month is celebrated by many activities with various ideas and themes for the younger generation. In 2013, Black History Month celebrates the 50th anniversary of the March on Washington at which Martin Luther King, Jr. gave his famous speech “I have a dream”. It also marks the 150th anniversary of the Emancipation Proclamation (解放黑奴宣言). The theme for Black History Month in 2014 is “Civil Rights in America” remembering the important milestones by African-Americans and others in the battle for civil rights and equal treatment under the law.

The day of my holiday arrived, but I wasn’t looking forward to it. I had little money and had only been able to afford to stay with my Aunt Rosa in Spain. So, I wasn’t really excited as I knew exactly what it was going to be like; Lots of noisy cousins and Aunt Rosa begged me to take her for a ride.

After I had checked in, I made my way slowly to the departure gate. As I was waiting to board the plan, I kept thinking about my ideal holiday destination; Jamaica, with its long, sandy beaches and crystal clear water.

As soon as the plane took off, I fell fast asleep and only woke to the sound of the announcement; “Ladies and gentlemen, please fasten your seat belts, as we will shortly be landing in Kingston.” I froze in my seat. Was I dreaming? Kingston? Jamaica? I had boarded the wrong plane!

Immediately after the plane landed, I explained the situation to the authorities. It seems there were also three of other passengers heading for Spain. Apparently it had been the airline’s fault, since the flight numbers for Spain and Jamaica were exactly the same! Therefore, with no flight to London for a week, the airline had no choice except to pay for our stay.

So there I was, lying on the beach, enjoying the music and marvelous food of Jamaica! As for Aunt Rosa, I suppose she just had to live without me!
