احتاجت الشعوب منذ القدم إلى التواصل فيما بينها, و الاستجابة لمتطلبات الحياة في الاستقرار السياسي و لذلك لجأت إلى تحقيق ذلك عن طريق ارسال الرسل و المبعوثين و هذا هو بداية ما عُرف فيما بعد بالدبلوماسية الحديثة و ظهور السفراء الذين تولوا هذه المهمة.والدولة العثمانية حظيت بعلاقات سياسية عديدة في الشرق والغرب و لذلك توجب عليها أن تتجه نحو الجانب الدبلوماسي من اجل توثيق هذه العلاقات و الاستفادة منها في الجانب السياسي والاقتصادي و إظهار هيبة الدولة العثمانية، وتجاوز الازمات التي تعرضت لها . و برزت اهمية هذه العلاقات الدبلوماسية في عهد السلطان سليمان القانوني (926هـ - 973هـ / 1520م – 1566م) وهو العصر الذهبي للدولة العثمانية, وبدأت الدول بإرسال السفراء و البعثات الدبلوماسية الى استانبول ، وحظيت هذه السفارات باهتمام كبير في البلاط العثماني ، وصاحب ذلك اقامة مراسم استقبال تناسب قدوم السفراء وتعكس اهتمام السلطان ورجال الدولة بهذا الامر وفق قواعد دبلوماسية محددة

The study sought to reveal the extent to which Egyptian and Saudi university students rely on influencer content on social media platforms and the relationship between this and their perceived credibility. It also sought to identify the motives and behaviors behind the respondents' use of influencer content on social media platforms. It also explored the most significant effects (cognitive, affective, and behavioral) resulting from the respondents' following of influencer content on social media platforms. The study relied on a descriptive approach using a questionnaire, applied to a sample of 450 people. The study also relied on the media dependency approach and the source credibility model within its theoretical framework. The study results confirmed: (1) The existence of a statistically significant positive correlation between the degree to which Egyptian and Saudi university students rely on social media platforms to follow influencer content and their level of credibility of that content. (2) The existence of a statistically significant relationship between the cognitive, affective, and behavioral effects resulting from Egyptian and Saudi university students' reliance on social media platforms to follow influencer content and their level of credibility of that content. 3) There is a statistically significant relationship between the dimensions of credibility (attractiveness, expertise, and trustworthiness) in influencers' content on social media platforms and the level of credibility of that content. These results indicate that Egyptian and Saudi university students prefer to follow content from influencers with high credibility.
